How JavaScript gets praised everywhere?

With the Initial release of JavaScript in 1995, it was primarily used for front-end development as it is a combination of CSS and HTML for dynamic and interactive web applications solution. Although, when we talk about web-JavaScript inevitably has supremacy in web development technologies.



After the release of Node JS in 2009, the “JavaScript everywhere” paradigm evolved into existence. This server-side programming thing allows consolidating web application development into single Programming unit which ultimately opens up the option for full stack development. NPM-Node’s Packages Manager is one of the largest eco-system of open-source libraries across the entire globe.

Why JavaScript:

• It can be used in both front-end and back-end in case of web development
• Regularity in version updates
• Used to work with DOM (Document Object Model- which is being used for displaying web pages) for responding to user interactions
• JavaScript offers a large variety of pool for frameworks and libraries on which developers can rely and create a complex application with fewer puzzling

Beyond the web application, JavaScript has a giant presence among cross-platform application development. Renowned standalone apps like GitHub, Slack, Skype, and Tidal are developed with the help of its Electron.js framework. Furthermore, we shortlisted most popular JavaScript, libraries and tools which has been accepted by famed developers; let’s take a deep dive for more transparency.
 

Package Manager and General Purpose Task Runners:

The package manager is group or collection of software’s which automatically executes the essential processes of installation, upgrading the existing version, configuring, and removing unnecessary computer programs from the OS in a steady way.

Testing Framework or unit

1] Mocha

Mocha is a highly preferred JavaScript test framework for Node JS programs, along with browser support, test coverage reports, asynchronous testing with use of any of assertion library.

Purpose behind using Jasmine:

• Originated from RSpec
• Less dependency with regards to DOM

Difference between Jasmine and Mocha Testing Frameworks:

• Jasmine framework has everything inbuilt consisting of assertion/ expectations and test double utilities whereas Mocha doesn’t have inbuilt support for assertion and test double utilities

• Moreover, if you choose Jasmine then you would probably use Karma (for assertion) Sinon( for fake servers) and else if you pick Mocha then you would probably use Chai (for assertion) Sinon (for fake server and test doubles) and Karma CLI (for test runner)

 

Final Thoughts:

As the abundance of frameworks and libraries are ruling the crowd, though React JS is somehow in the front line of web development approaches; Vue JS also takes its footprints forward. Deciding the best development choice is completely relying on what type requirements have to fulfill. Angular JS is also popular due to its SPA functionality which offers dynamic and fascinating experience to customer base; although when it comes to real-time and influential framework then relying on Node is an optimistic choice, as it has a vast set of functionalities for selecting Node over any other frameworks.
