Many years ago web designers were limited to JavaScript when adding functionality to web sites. This was before the official release of HTML5 and CSS3. JS added oomph to any website, making it more appealing and sexy. If the user disabled JS in the browser then web sites had to be functional without it.
Will JavaScript ever die? must have been on many peoples minds. Well, the answer to that is no. JavaScript has become popular over the years. JS Frameworks like jQuery, MooTools, _Underscore, Backbone gave JS a new lease of life. These 1st generation frameworks are still used in today’s environments.
