JavaScript is a popular scripting and programming language which handles user interaction in websites and web applications. It is a simple language, easy to learn and code and at the same time powerful enough to handle large business requirements. It can be used in web applications, mobile and game development.
JavaScript makes web pages dynamic. HTML provides the structure of a web page. It is like the completely static backbone of websites. CSS styles the various components of the website, like adding colors, background images, adjusting margins, etc. JavaScript provides dynamic nature to the website, animations, video/audio elements, etc.
JavaScript is technically a front end scripting language. However, with the launch of Node.js, JavaScript is increasingly being used in server side development. JavaScript, in today’s world, is used in both frontend and backend development.
When it comes to asynchronous programming using JavaScript, it becomes increasingly hard to understand the concept of async, await and callback methods. This is particularly because JavaScript is a single threaded language which makes its asynchronous nature different from other languages.
If you’re learning on your own, it can take six to nine months to become proficient in JavaScript. In this much time, you can easily learn how to develop logic and code in JavaScript. You can also learn the internal implementation of JavaScript which includes the concept of call stack, callback methods, web APIs, etc.
