Advantages of JavaScript

Speed: Being client-side, JavaScript is very fast because any code functions can be run immediately instead of having to contact the server and wait for an answer.

Simplicity: JavaScript is relatively simple to learn and implement.

Versatility: JavaScript plays nicely with other languages and can be used in a huge variety of applications. Unlike PHP or SSI scripts, JavaScript can be inserted into any web page regardless of the file extension. JavaScript can also be used inside scripts written in other languages such as Perl and PHP.

Server Load: Being client-side reduces the demand on the website server.

Libraries: Many code libraries for JavaScript functions are freely available. These allow developers to provide extensive levels of functionality without having to implement the details themselves.

Content Management: JavaScript allows developers a level of flexibility in terms of the information that is displayed within a page.

Styling: JavaScript can alter the style of website elements as users interact with them. Common uses of this technique include altering the appearance of an interactive item such as a menu option when the user moves her mouse on and off it, changing the colors and images displayed within it. JavaScript can also create animations within Web pages, making the appearance and disappearance of page elements smoother and more engaging.

Interactivity: JavaScript functions often enhance interactivity with a Web page. Developers can create JavaScript functions to implement interactivity within user control features.
