Why did Javascript come into the picture?

In 1995, the browser “Netscape Navigator” was popular. A Netscape programmer named Brendan Eich developed a new scripting language in just 10 days. It was originally named Mocha, but quickly became known as LiveScript and later, JavaScript. JavaScript was born, merely as a scripting language to validate forms on the client-side. After then JavaScript passed through many evolutions to become a strong programming language that is being used by many top leading Websites and Web Applications.
