JavaScript is the scripting language of the Web!
JavaScript is used in millions of web pages to improve the design, validate forms, detect browsers, create cookies, and much more.
JavaScript is the most popular scripting language on the Internet, and works in all major browsers, such as Internet Explorer, Mozilla, Firefox, Netscape, and Opera.
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 Netscape Navigator and Microsoft Internet Explorer.
This could be attributed to the slow progress of JavaScript through the standards bodies.
