I want to say something in JavaScript. Some think that JavaScript works only in the form of web page form validation and some dome manipulation. And it is a client side language that can run only in the browser.But the ideas are 100 percent wrong. From server side and network programming, mobile and desktop app development, game development to Internet of Things, machine learning, this JavaScript will also be seen. And it has been built on intermediate language and has been developed on some sub languages like Capsiscript, TypeScript etc.
