Answer 1

What are the advantages of using JavaScript?
Less server interaction − You can validate user input before sending the page off to the server. This saves server traffic, which means less load on your server. Immediate feedback to the visitors − They don't have to wait for a page reload to see if they have forgotten to enter something. Increased interactivity − You can create interfaces that react when the user hovers over them with a mouse or activates them via the keyboard. Richer interfaces − You can use JavaScript to include such items as drag-and-drop components and sliders to give a Rich Interface to your site visitors.
What are disadvantages of using JavaScript?
Client-side JavaScript does not allow the reading or writing of files. This has been kept for security reason. JavaScript can not be used for Networking applications because there is no such support available. JavaScript doesn't have any multi-threading or multiprocess capabilities.
