JavaScript is THE scripting language of the Web.
JavaScript is used in billions of web pages to add functionality, validate forms, communicate with the server, and much more.
JavaScript is the most popular scripting language on the Internet, and works in all major browsers, such as Edge, Firefox, Chrome, Opera, and Safari.

Are Java and JavaScript the Same? NO!Java and JavaScript are two completely different languages in both concept and design!
Java (developed by Sun Microsystems) is a powerful and much more complex programming language—in the same category as C and C++.
JavaScript should not be confused with Java.
JavaScript is a registered trademark of Sun Microsystems.
It was used under license for technology invented and implemented by Netscape Communications and current entities such as the Mozilla Foundation.
JavaScript vs JScript
JavaScript originated from Netscape, and for a time, only Netscape products supported it.
Microsoft now supports it, but as a “work-a-like” called JScript.
The resulting inconsistencies make it difficult to write JavaScript that behaves the same in both Mozilla Firefox and Microsoft IE.
This could be attributed to the slow progress of JavaScript through the standards bodies.
