JavaScript: How Industries Are Using JavaScript To Solve Their Challenges
JavaScript has become one of the most popular programming languages of all time. It all started in the year 1995 when Brenda Eich created JavaScript in a span of 10 days. I have written a blog on introduction about JavaScript and how industries nowadays solve their challenges using JavaScript.
What is JavaScript?
JavaScript is a text-based programming language used both on the client-side and server-side that allows you to make web pages interactive. Where HTML and CSS are languages that give structure and style to web pages, JavaScript gives web pages interactive elements that engage a user. Common examples of JavaScript that you might use every day include the search box on Amazon, a news recap video embedded on The New York Times, or refreshing your Twitter feed.
Feature of JavaScript
- Scripting language and not Java: In fact, JavaScript has nothing to do with Java. Then why is it called “Java” Script? When JavaScript was first released it was called Mocha, it was later renamed to LiveScript and then to JavaScript when Netscape (founded JavaScript) and Sun did a license agreement.
- Object-based scripting language supports polymorphism, encapsulation, and to some extent inheritance as well.
- Interpreted language: It doesn’t have to be compiled like Java and C which require a compiler.
- JavaScript runs in a browser: You can run it on Google Chrome, Internet Explorer, Safari, etc. JavaScript can execute not only in the browser but also on the server and any device which has a JavaScript Engine.
What is JavaScript used for?
1. Adding interactive behavior to web pages.
2. Creating web and mobile apps.
3. Building web servers and developing server applications.
4.Game development.
Companies Using JavaScript
Google’s search results spring up as your typing gets there with JavaScript. The Gmail web client is powered by JavaScript. Google Docs? Yeah, that’s JavaScript too.
Google develops and usually opens sources its own JavaScript tools. The most obvious example is AngularJS. Angular is used most prominently in Google’s DoubleClick advertising platform, but it’s also one of the most popular front-end frameworks available. It’s even part of the MEAN stack. Google’s more intensive services, like Google Docs, use Closure Tools. This set of tools compiles JavaScript into a lower-level faster form more suited for rich and highly responsive web applications. There’s another big point to touch on. Google developed Chrome. Chrome is a web browser, needed a JavaScript engine, so Google also made V8. V8 not only powers Chrome, it’s at the heart of NodeJS. So, without Google, there would be no Node.
You’re probably aware that Facebook uses JavaScript. It’s kind of hard to miss. What’s probably not as obvious is exactly how much JavaScript goes into making Facebook and how much Facebook is involved in JavaScript development. Try disabling JavaScript in your web browser and going to Facebook. The website will actually stop you from logging in because it won’t work without JavaScript.You may have noticed the way that Facebook loads. Each piece of the page is separate. Facebook has invented its own way of breaking down and delivering sections of JavaScript separately. In an odd way, each section of your Facebook page is a collection of independent JavaScript applications.
It doesn’t stop there. Facebook created React, one of the most popular front-end frameworks. Facebook uses React on Facebook.com as well as Instagram and WhatsApp.
