Client Side Scripting Language


  • Client-side scripting language is source code that is executed on the client’s browser instead of the web-server.
  • It allows creating faster and more responsive web applications.
  • Client-side scripting(embedded scripts) is code that exists inside the client’s HTML page.
  • This code will be processed on the client machine and the HTML page will not perform any Post Back to the web-server.
  • Traditionally, client-side scripting language is used for page navigation, data validation and formatting. The language used in this scripting is JavaScript. JavaScript is compatible and is able to run on any internet browser.


  1. Helps to develop fast and responsive web site.
  2. Helps to optimize the application.
  3. Helps in validating and verifying the input data
  4. Can call various services available in the network.
