Scripting languages can run in different environments:

• Client-Side Scripting:

  • Code is executed on the user's computer, typically within a web browser.
  • JavaScript is the most common client-side scripting language.
  • Pros: Can respond quickly to user actions without needing to communicate with the server, reduces server load, allows for richer user interfaces.
  • Cons: Dependent on the user's browser capabilities, code is visible to the user (can be viewed/copied).

• Server-Side Scripting:

  • Code is executed on the web server.
  • Examples: Node.js (JavaScript), Python (Django/Flask), PHP, Ruby on Rails.
  • Pros: Can access databases and other server-side resources securely, code is not visible to the client, can handle complex business logic.
  • Cons: Requires a round trip to the server for every dynamic request, which can introduce latency.

JavaScript, with Node.js, can be used for both client-side and server-side scripting, making it a full-stack development language.
