A STUDY OF NODE.JS

The world is raving about Node.js. It is increasingly being used for traditional websites and API applications. Extremely popular, it uses the JavaScript as their main application to create new applications. Additionally, JavaScript is the only choice for web applications in the web browser. It has a wonderfully strong and robust Framework that endears itself to all developers. A typical example of a User is the Netflix. Netflix is the world’s leading Internet television network with over 117 Million users on April 19, 2018. Huge amounts of A/B testing are used to provide an unbeatable experience for the users, who just love its high capacity data-driven platform. This is a micro portrait of the JavaScript environment package Node.js explained.

What is Node.js

Node.js is a Server Environment which is Open Source. It is free, utilizes JavaScript and works easily on an array of platforms, like Mac OS X, Linux, UNIX, and Windows. Node.js uses asynchronous programming. A simple daily task could be something like opening a server file and returning it to the client. This file request would be handled by ASP or PHP as follows:

  • It propels the tasks to the computer’s file system.
  • Allows the system to wait until the file is opened and read.
  • The content is sent easily to the Client.
  • It then readies itself to take care of the upcoming requests.

But Node.js manages the file request differently, as follows:

  • Node.js can hurl the task to computers file system.
  • Node.js readies to get a hold of the subsequent request.
  • The server returns the content instantly to the client after opening and reading the files.

It must be noted that Node.js completely diminishes the wait period and takes on the next requests. Its speed of operation has to be seen to be believed. Node.js runs as asynchronously programming, non-blocking, and single threaded, making it supremely memory efficient. Node.js files have the ability to execute different level of events at ease. Ideally, ones that try to look p for port access on the server. But Node.js files are required to be kicked off on the server. Node.js files have extensions ‘.js’. But there are several tasks that node.js can perform, and some of these are:

  • Collection of form data.
  • Perform all actions on the server – opening, creating, reading, writing, deleting and closing files.
  • Addition, deletion, and modifying data in the database.
  • Creating a dynamic page content.

How It Works

Node.js is an Open Source development platform for executing JavaScript code Server-side. It is useful for developing applications which require a persistent connection from the browser to the server. It is often used for Real-time applications, such as, news feeds, web push notifications, and chat. It is even used by dating sites and applications such as the prominent UK sex site MNFUK amont others. For the beginner, Node.js is an environment built on Chrome’s V8 JavaScript Engine. The JavaScript is the only language that Node.js supports naturally, but several compile-to-JS languages are available. Due to this, Node.js applications can be written in ClojureScript, Dart, TypeScript, CoffeeScript and many others.

Special Features

Some of the best features of Node.js are discussed below:

  • Framework: Node.js is still extremely popular. Its relevance in the market is because of its clear increase in productivity. Node.js, working on JavaScript, has become a full stack development language. Several others like React, Angular and Vue are Front-end Frameworks/Libraries, but Node.js is the only JavaScript based Back-end Framework.
  • Security: A Node.js core is fully secure. But a problem exists with installation of third-party packages. The way these are configured, installed and deployed may require additional security to protect web applications from the hacker.
  • Multi-threading: JavaScript code executed by Node.js runs practically in a single thread. But Node.js itself is multi-threaded. It’s I/O and other such operations run from a Thread Pool. And because of this, a kind of multi-threading with C++ and native Node.js C++ Development can be achieved.
  • Node.js Vs PHP: Some programmers prefer PHP because it is easier to learn than Node.js, and features an integrated Database. But Node.js is far more extensive than PHP. Node.js is also blindingly faster compared to PHP, and these two features often make Node.js the first choice.
  • Use: Node.js uses an event-driven, non-blocking I/O model, that make sit light-weight and efficient, perfect for Data-intensive, Real-time applications that run across distributed devices.
  • Scalability: Node.js offers easy scalability.
  • Performance: Node.js is known for high performance.
  • Support: Node.js has the support of a large and active community.
  • Ubiquity: In the past, it was notoriously common to see Java Code, like, Enterprise Java Beans (EJB) or Servlets, in the Server-side and JavaScript running in the browser. Now, Node.js runs on the sides, Client and Server, and same Source Code running. Basically, the code is written once only, and then it can be run on both sides. This is called ‘Ubiquity’.
  • Node Package Manager (NPM): NPM is the root of almost all deployment systems for Node.js, and underlies the many PaaS (Platform-as-a-Service) providers for Node.js. Its simple and dependable package management has supported the Node Ecosystem grow spectacularly in recent history.

The Future of Node.js

Node.js has the fastest runtime among all programming languages, thanks to the dominant language and also the support and assistance by the major browsers. The future appears to be challenging and strikingly brilliant for Node.js in the front-end world, as it seems like no front-end improvement is possible without Node.js. Development with Node.js lives up to its high reputation as the new standard for Enterprise Applications. Some experts and top drawer developers are even beginning to claim that it is so powerful, that it has the potential to replace Java for good. This would dethrone Java as the most trusted language, which is a spot that Java has held since 1995. For example, recently PayPal transferred all apps from Java to Node.js, for which the main reason is the ability of Node.js to iterate rapidly.

php frameworks compared

PHP Frameworks Compared

PHP stands for “Hypertext Pre Processor”. Actually, PHP originally stood for “Personal Home Pages”. So it could be called a “backronym”, or perhaps a “recursive acronym”. It is an open source Server Side scripting language. Its extreme popularity is evidenced by the fact that over 80% of all websites were using PHP as of October 2018. But why use PHP at all? This is because a PHP framework provides the most convenient structure for a logical and streamlined development. They can work at extreme speeds. Businesses are able to meet their necessary performance using PHP. The usage in 2019 was close to that in 2018, and there is no doubt that, barring a brand new framework which betters PHP, this will be the framework of choice in the years to come. In this review, we will study PHP frameworks compared, and find out why PHP is so popular with developers.

Understanding PHP

PHP is a server side scripting language, which is to say, it is interpreted on the Server only, whereas a Client side scripting language, like JavaScript, has to be interpreted by the Client application. But what is a “Scripting Language”? This is a language that interprets scripts at runtime. These scripts are usually embedded into other software environments. PHP codes may be executed with a CLI (Command Line Interface), embedded into HTML code, or used in combination with web template systems, web content management systems, or web frameworks.

Scripting Languages

A Scripting Language is a language that interprets scripts at runtime. It is a set of programmed instructions embedded into other software environments. The use of Scripting Language is complemented by the use of Programming Language. A comparison between the two shows that while Programming Language has all the features necessary to develop complete applications, Scripting Language is generally used for routine tasks only. The Code in a Programming Language must be fully compiled before it can be executed, whereas the Code in Scripting Language is executed without compiling. A Programming Language can be used on its own, without embedding into other languages. But Scripting language is generally embedded into other software environments.

Advantages of PHP

  1. PHP is cost effective. Most Web hosting Servers support PHP by default unlike ASP which needs IIS.
  2. PHP is a large community document.
  3. PHP has been and will be regularly updated to ensure it uses State-of-the-Art advancements.
  4. PHP is Open Source and free.
  5. Learning PHP means a short learning curve when compared to other languages such as ASP, JSP etc.
  6. Operationally, since PHP is a Server Side Scripting Language, it needs to be installed only on the Server’s end. When Client computers request for resources from the Server, PHP does not have to be installed at the Client Side. A Web browser would be sufficient.
  7. PHP is a ‘Cross Platform Language’. The application can therefore be deployed on-to a large number of different Operating Systems. Platforms that can be accessed include Mac OS, Windows, Linux, Linux Kernel based Android etc.
  8. PHP can work hand-in-hand with MySQL, so can work comfortably with it. Of course PHP can still be used with Oracle, MS SQL Server, ODBC and Postgres.

Frameworks Compared

Some of the most well known PHP Frameworks Compared now follows:

  • LARAVEL: This is the most widely known and used PHP frameworks of all. But LARAVEL does not work on Shared Hosting plans. It can organize files and code, and has rapid application development. The Architecture is NVC and PHP 7.1.1. Regarding unit testing it is FAST on HHVM. It has the best documentation of any such application, with a high level of abstraction. Stronger encryption packages (ORM) and Payment integration with STRIPE is very powerful. It has enormous out-of-the-box functionality. Overloading capabilities using dynamic methods are available.
  • CODEIGNITER: Universally known as friendly to beginners, CODEIGNITER is particularly helpful for developers who are in a hurry. Data Bases like MySQL and standard Web Hosting Services can easily be adapted. All non-MVC frameworks can be left far behind. CODEIGNITER provides good documentation and (Long Term Support) LTS. CODEIGNITER does not lend itself easily for Unit Testing, and has only a few Libraries in-built into the framework. But it is light (it is only 2mb in size) , easy to setup and extremely rapid in action.
  • CAKEPHP: CAKEPHP ropes PHP 5.5+ with its modern framework. It uses a Scaffholding system, which allows very fast builds. It has an MIT license for commercialized Web applications. But it is not as good for constructing Restful APIS as LARAVEL and its sister software. It achieves Validation and Authentication, Caching, Data Base access with ease, as these features are all built-in. It has extensive safe-keeping tools such as CSRF, SQL Injection Prevention, Cross Site, Scripting Prevention etc.
  • ZEND: ZEND is not ideal for Rapid Application Development, but it is superb for enterprise applications. It has vast components for Validation, Feeds and Forms. Surprisingly, this framework has been used in the development of some very popular sex dating apps and free hookup sites like Fuckbook and Local Sex App. Many of the functions and advantages are utilized well in these adult app platforms.
  • FUELPHP: It has Restful APIS Building, URL Routing and Authentication Packages (Caching is optional). It is modular with integrated ORM. Reviews of its newer version reveals that it can be installed using Composer and one installation will be able to support multiple applications. It will be fully object oriented.
  • PHALCON: This is a lightning fast PHP Framework Application. It is most unusual in that it is based as a C-extension. It is Auto Loading, has excellent security features built in. it is not as Open Source as LARAVEL and it does not work with HHVM. It has lots of documentation and is very Developer friendly.
  • SYMPHONY: This is a high performance framework, stable and well documented. It is also well maintained and supported. But it has a steep learning curve and it does not support MVC. It has Byte Code Caching.

Developers prefer PHP Frameworks because they are structured and efficient, as well as fast track. PHP is by far the acknowledged leader of Frameworks for Developers around the world.

uncommon programming languages you should know

Uncommon Programming Languages

There is a number of programming languages that exist today. Among them, some are front-end and others are back end programming languages. Commonly everybody heard about languages like Java, C, and C++ since they are very popular languages. Apart from these, even python, Ruby, and Perl have gained the highest popularity in recent years. But there are many uncommon programming languages which are used by never heard and they are not familiar.

Here is a list of programming languages that are uncommon.

Rust

rust programming language

This programming language is sponsored by Mozilla and it focuses on memory safety, type safety, and concurrency. Apart from this, it also focuses on performance. You can utilize this programming language for distributed server and client applications. It is also used in reliable system-level programming.

Hack

hack open source programming language

This is another uncommon programming language which is created by Facebook. This is a dialect of PHP and used for hip-hop virtual machines. By utilizing this programming language, developers can create complex websites that work really fast. There is no need to compile the programs written in this programming language. The hack is one of the statistically typed programming languages which allow dynamic coding similar to PHP.

Ada

ada programming language

This programming language offers plenty of features like the highest flexibility for scale-up and to meet needs. It also helps in the avoidance of namespace pollution and data abstraction. Ada is best suitable for information hiding semantics, concurrency support, reusability, and even for methodology neutrality. It can be utilized for real-time support and safety-critical support.

Haskell

haskell programming language

If you are searching for a purely functional programming language, then Haskell is the right choice. This programming language called Haskell is very lazy and it is statically typed. It features typed inference and it offers simple and elegant amazing syntax. The speed offered by this programming language will definitely amaze you.

Erlang

erlang programming language

This programming language is created by Ericsson Computer Sciences Lab. This programming language is mainly developed to the problem of concurrency. This programming language is freely available and it is open source. Erlang offers multithreading and it makes use of a virtual machine like Java. This programming language is specially built for embedded systems and it is the choice for very robust servers. There are many applications developed by this programming language but even after that, this is an uncommon programming language. Facebook chat is one example of applications developed by Erlang. This programming language is suitable only for certain tasks and not for all.

Racket

If you are searching for a multi-paradigm language then you have come to the right place. This programming language is based on the rudiments of the Lisp/Scheme. This programming language comes with a goal and it serves a platform for language creation, implementation and design. The racket is the programming language behind Wikipedia. So, this programming language can be used for clear and well-organized documentation.

IO

This is one of the programming languages which are recently released. IO offers prototype-based object model and this model is very similar to that of Self and NewtonScript. Simplicity and minimal syntax are the two best features of this programming language. IO is easy to learn and it is best suitable for general-purpose programming.

Groovy

This is also a new programming language and it also comes with a prototype-based object model like IO.

Scratch

This programming language is released by MIT Media Lab and is designed for children of age 8 and 16. There is no typical syntax for this programming language. This language is designed for kids and it makes it more thinker able and language is more meaningful for them. They will like it because this programming language is more social compared to other programming languages.

Dart

This programming language is from Google and this was once well known and popular for web development. Dart was about to replace JavaScript but that never happened. Later it got left behind by JS. Later it went under remodeling and joined with CoffeeScript. There are two popular customer-facing web applications called AdSense and AdWords and these make use Dart. There are plenty of users for Dart who are outside Google. Companies like Blossoms and Workiva make use of this programming language. Even though it comes with stronghold within Google, it should be sold to outside developers.

Q

This is one of the programming languages developed by Kx Systems. Kx is one of the very popular data analytics vendors. This language offers multiple approaches when it comes to solving a problem and it makes it versatile.

Clojure

This programming language is mainly designed for offering the highest concurrency. This language is a variation of the Lisp programming language. This language runs on Java Virtual Machine and when you use this language you get Java interoperability for free.

Bottom Line

These are some of the best languages which are uncommon but are in use in one or other applications. Since they are suitable for limited applications, they have remained uncommon to common developers but they are used in the best way.
