The Future Of JavaScript

The Future Of JavaScript

Introduction
JavaScript is a high-level, dynamic, untyped, and interpreted programming language. It has been standardized in the ECMAScript language specification. Alongside HTML and CSS, it is one of the three core technologies of World Wide Web content production; it is supported by all modern Web browsers without plug-ins in addition to being the only cross-browser scripting language.
Beginning of JavaScript
JavaScript was originally developed in 10 days in May 1995 by Brendan Eich, while he was working for Netscape Communications Corporation. JavaScript has become one of the most popular programming languages on the Web.
Features of JavaScript
  • Imperative and Structured (Support much of C Programming feature).
  • Dynamic typing.
  • Run time evaluation.
  • Object Oriented with the help of prototypes.
    • Functions as object constructors
    • Functions as methods
  • Deligative
    • Functions as Roles (Traits and Mixins)
    • Object Composition and Inheritance
  • Run-time environment
  • Variadic functions
  • Array and object literals
  • Regular expressions
ES6 becomes the latest JavaScript standard and added much more power to JavaScript. Here are some of the features:
  • Default Parameters
  • Template Literals
  • Multi-line Strings
  • Destructuring Assignment
  • Enhanced Object Literals
  • Arrow Functions in ES6
  • Promises
  • Block-Scoped Constructs Let and Const
  • Classes
  • Modules

Usage of JavaScript worldwide
JavaScript is everywhere. Most of the modern browser support JavaScript and it is also supported in mobile devices. JavaScript is the most popular and trending language on GitHub.

Tools Build On JavaScript
Look at a mind map of tools build on JavaScript languages and used in different areas.
Over the past decade, starting with jQuery empowering Web developers with client-side scripting, every popular plug-in has filled another gap in the language and its capabilities.
React.js, Angular and new wow Vue framework extend HTML syntax to JavaScript while streamlining the coding process with data binding and dependency injection.
  • D3.js,C3.Js, Chart.Js, Tui charts, Highcharts Data visualization library extends how data represented on the Web.
  • PDF.js Built with HTML5 and used for parsing and rendering PDFs.
  • Handlebar.js, Mustache.js, and Jade are template engine to render HTML based on JSON data.
  • CoffeeScript and TypeScript are compiling syntax to JavaScript to support type checking and scoping.
  • Backbone, Ember, and Grunt make Web application development run smoother and faster.
  • Apache Cordova and Bootstrap open JavaScript’s Mobile Web and app development possibilities.
  • Node.js, Express.js gives JavaScript the cross-platform runtime to conquer servers, embedded devices and more.
  • MongoDB, Postgresql gives power to backend open source database.
  • NPM and Bower are package management tools.
  • Grunt.js, Gulp.js, and Browserify.js are building automation tools.
  • Cucumber.js, Jasmine, Jest, Mocha, and Q-Unit are testing framework.
  • Underscore.js and Lo-Dash is a powerful JavaScript utility library.
It's used as a scripting language in Unity3D for Game development.
Meteor Framework for building Full Stack real-time application with the help of Node.js, MongoDB and Template Engine(React, Angular or Blaze or Vue).
Cylon.js is a JavaScript framework for robotics, physical computing, and the Internet of Things. It makes it incredibly easy to command robots and devices.
GraphQL is also trending and most emerging data layer technology which is used in creating Enterprise ready API in replacement or superset of REST API.
It is also used to control hardware https://tessel.io/ or http://www.espruino.com/
There are many more tools which are built on JavaScript language nowadays.
