Why Use Javascript?
People often confuse JavaScript with the language Java, both are different, and there is no need for you to get confused about it. Initially, this JavaScript was named LiveScript, but it was tough for people to understand it. That’s when they started calling it younger brother of Java, and that’s how it got the name JavaScript.
Any device that has a JavaScript engine can now run this language with ease. Be its browser, server, or equipment; if it has the JavaScript engine, it is good to go. There is an embedded engine in the browser, which is also called as “JavaScript Virtual Machine.” Each of the engines has a different name for its virtual machine; in Chrome and Opera, it is called V8, and in Firefox, it is called SpiderMonkey.
