JavaScript and its Industry Use Case:
What is JavaScript??
JavaScript (JS) is one of the most popular programming languages, commonly used for creating interacting websites. it is is a text-based programming language used both on the client-side and server-side. Whereas HTML and CSS give a website structure and style, JavaScript lets you add functionality and behaviours to your website.
JavaScript is a cross-platform, object-oriented scripting language used to make webpages interactive (e.g., having complex animations, clickable buttons, popup menus, etc.). There are also more advanced server-side versions of JavaScript such as Node.js, which allow you to add more functionality to a website than downloading files. Inside a host environment (for example, a web browser), JavaScript can be connected to the objects of its environment to provide programmatic control over them.
Features of JavaScript:
- Light Weight Scripting Language because it is not a general-purpose language so it has a limited set of libraries, and is only made for handling data at browser.
- It Supports dynamic typing so the type of the variable will be defined on the basis of stored value.
- Object-Oriented programming Support.
- Platform-Independent.
- Provides more control to the browser
- It can validate user input.
- Prototype-based language.
- Interpreted Language.

How and Where big companies are using javascript?
How doesn’t Google use JavaScript? Seriously, it’s everywhere. Google’s search results spring up as your typing get there with JavaScript. The Gmail web client is powered by JavaScript. Google Docs? Yeah, that’s JavaScript too.
Google develops and usually open sources it’s 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, being 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.
Facebook is the most popular social networking site where we can connect with our friends, relative, and other people. we can chat, share our content, comment on posts, and, etc. Facebook is using JavaScript for providing new interacting features for users
Facebook has also created React, an open-source JavaScript framework. React is a popular open-source JavaScript library that performs data viewing with the help of HTML. It is also known as ReactJS and React.js. They are using it for developing websites for a lot of their products like Instagram, Messenger, Whatsapp.
The Facebook development team used React Native to create their current mobile applications for both iOS and Android. Both mobile apps were created by the same development team using a single JavaScript language, so they share common features and work in the same intuitive manner. the deployment of native applications has improved Facebook’s user experience.
