Javascript An elite programming language

Mar 5, 2017

What has happened so far in the past?

When the Java applets failed, it allowed Javascript to grow and become the most popular language for the WEB. Javascript is a high-level, interpreted or just-in-time compiled, programming language created by Brendan Eich in 1995 during his time at Netscape Communications. It was inspired by Java, Scheme, and Self.

JavaScript is a prototype-based, multi-paradigm, dynamic language, supporting object-oriented, imperative, and declarative (e.g. functional programming) styles. It was mostly scripting programming language used on the web but now it has become a mammoth.
Javascript was the language which could have been run only on browsers and there were different browsers out in the market with their own specifications. To make it run on all browsers, There was a need for a platform where all the javascript features could have been standardized, thus ECMA( European Computer Manufacturers Association) was formed. That is why javascript is also called as ECMAScript.
Apart from JavaScript, there are other well-known implementations from ECMAScript such as JScript, ActionScript. An update, released each year with new features, is named as an updated version. A major release in the year 2015 was known as ES6. The future release is called as ESNext.
ES6 is not well supported by most of the browsers, so we need Babel or Traceur which is a javaScript compiler that converts the modern javascript to the supported javascript.

How does the present look?

Large communities play an important role in shaping any programming language and javascript has a huge community support. The current release is ES10, after ES6 the language has become mature and opened the door of opportunities for developers to experiment and build different pieces. It is now possible to run javascript on Server Side as well as on Client Side, and even on the Mobiles, Desktops, and IOT. It has been the most loved programming language for 2017 and 2018, according to StackOverflow.

Let us have a look where we can use javascript presently.

1. Server Side

Nodejs

Nodejs is the javascript runtime built upon Chrome’s V8 engine which allows running javascript on the server side, Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

With these, there is an ocean of opportunities for a javascript developer to become a full stack developer by using the same programming language for the backend development. With Nodejs we can use javascript for Machine Learning, Artificial Intelligence, and IOT.

Some major tech giants such as Netflix, Linkedin, Walmart, Trello, Uber, PayPal, Medium, eBay, NASA have put faith in Nodejs. PayPal developers were able to write 33% fewer lines of code and use 40% fewer files while building the app twice as fast despite doing so with fewer people. Response time decreased by 35% which resulted in the pages being served 200ms faster. In the case of online payments, each second makes a difference.

2. Client Side

  • Reactjs – This is a javascript library, built by Facebook to create a Single Page Application, is the most frontend library out there and it is so rigid that one can easily build a high level, scalable and robust applications. Instagram has been built completely on React.

  • Vuejs  – Another elite in the league which can be used to create a robust Single Page Application.

There are other frameworks which can be used to create a SPA. With the Nodejs, we can run codes on the server side as well which is an added advantage.

3. Mobile

  • React Native– One can use React Native to build an advanced mobile application and maintain just a single codebase to seamlessly build a cross-platform mobile application in javascript. AIRBNB has built their mobile application with React Native and which is working pretty efficiently.
  • Ionic + Angularjs  - We can also develop cross-platform mobile applications with Ionic and Angularjs.
  • Apache Cordova, PhoneGap, and others  – These popular frameworks could be used to develop cross-platform mobile applications in javascript.

4. Desktop

ElectronJs

We can now build cross-platform desktop applications with HTML5, CSS3, and Javascript. Slack desktop application is built with Electronjs, VSCode-a popular code editor-is also built with Electronjs.

5. Database

ElectronJs

MongoDB and CouchDB a NoSQL database uses javascript as their scripting language.

6. Machine Learning

ElectronJs

It is now possible to shift towards machine learning and neural networks with libraries such as Tensorflowjs and Brainjs.

7. Internet of Things

We can now fly a robot or drive a car with the IOT libraries of javascript. Jhonny-five, Cyclone.js are some good libraries out there.

8. ChatBots

Chatbots are the next wave in marketing and interactive tech. Just about everyone is on a chat app.
Botpress is a framework for creating and managing chatbots using javascript. Chatbot-as-a-service products use standard web protocols, which makes javascript a perfect choice for them.

9. Games

With the introduction of Canvas in HTML5 there is an ocean of opportunity out there for javascript developers to utilize this to develop games.
Babylon-js, Threejs, Impact.js are one of the great frameworks to develop high-end interactive games.

What does the future hold?

Progressive Web Apps (PWA) are the future of web development and big companies are already putting the efforts to use javascript to create PWA’s with SPA libraries.
As the javascript continues to grow and there is no other out there on the web to compete with it, javascript has a bright future. A javascript developer can put in some extra efforts to learn the libraries or frameworks which will be much more rewarding than learning a completely new language and for tech companies hiring a developer with expertise in a single multipurpose programming language will be definitely plus point. It is easier to maintain the code base, as the same code can be shared on the frontend as well as the backend.
