Java Script in 2019

 

What is JavaScript

             JavaScript is a programing language specially used in web development. It helps developers to created web sites with dynamic content. It’s a single threaded language which supports both object-oriented and structured programming. The standard for the javascript programming language is ECMAScript. Most of the modern web browsers support ECMAScript 5.1 features. The latest version of the ECMAScript is ECMAScript 2015, also known as ECMAScript 6.

Where JavaScript Runs

Javascript is a client-side programming language. So it runs in the web browser using a javascript engine. Javascript engine is a program that complies javascript codes and executes them. Google Chrome uses V8 engine and Firefox has SpiderMonkey.

From Client Side to Server Side

Languages like Java, C#, and PHP are the popular server-side languages which use to programme the back-end of web applications. Recently javascript has come into the scene in the back end development. Compared to javascript, Java or C# is way more powerful languages. But Javascript is getting popular because both front end and back end can be handled by javascript. Javascript is run on servers(or anywhere other than web browsers) with the help of Node.js.

Node.js is the run time environment that use to run javascript code in the server. It’s built on Chrome’s V8 javascript engine.

Trend in 2019

Day by day technology gets updated. New programming languages and frameworks come to the scene. But still in 2019 javascript remains the no.1 programming language according to the survey carried out by stack overflow at the beginning of 2019. And also in this same survey javascript frameworks occupied the first three places of the most popular libraries and frameworks category. Those three libraries are Node.JS, Angular and React.

Should You Prioritize JS?

It depends on who you want to be. If you want to be a front end developer javascript is an obvious choice. There are huge opportunities in the job market for javascript developers. Also, js has strong community support.

But only 0.6% of severs use node js. And also if you want to build applications related to IoT, machine learning, video games, virtual reality, numerical computing, etc. Javascript is not the ideal choice. So I feel that it’s not worthy to spend huge time on learning javascript if you’re not planning on front end web development
