 Top Questions and Answers for the 2021 JavaScript Interview Questions

JavaScript is a very powerful language for client-side scripting. JavaScript is used specifically to enhance a user’s engagement with the webpage. In other words, with the assistance of JavaScript, you can make your website more vibrant and interactive. In-game development and mobile device development, JavaScript is also commonly used.

In 1995, Brendan Eich invented JavaScript, which appeared in Netscape, a common browser at the time. The language was originally called LiveScript and later renamed JavaScript. There are many programmers who assume that the same is true for JavaScript and Java. JavaScript and Java are, in fact, very unrelated. Java is a programming language that is very complex, whereas JavaScript is just a scripting language. JavaScript’s syntax is also inspired by the C programming language.

JavaScript, being a scripting language, does not operate on its own. The browser is directly responsible for running the code for JavaScript. The script is sent to the browser when a user requests an HTML page with JavaScript in it and it is up to the browser to run it. The principal benefit of JavaScript is that JavaScript is supported by all modern web browsers. So, you don’t have to think about Internet Explorer, Google Chrome, Firefox, or some other browser that your website visitor is using. It will support JavaScript. On any operating system, like Windows, Linux or Mac, JavaScript also runs. JavaScript thus overcomes the key drawbacks of VBScript (Now deprecated) which is limited to just IE and Windows.

Also, JavaScript is not exclusive to browsers. The speed and small memory footprint of JavaScript creates more and more uses for it as opposed to other languages, From automating repetitive tasks in programs such as Illustrator, to using it with a standalone parser as a server-side script.There’s a big open future.
