Server-Side Scripting vs. Client-Side Scripting — What's the Difference?

Difference Between Server-Side Scripting and Client-Side Scripting


Key Differences

Server-Side Scripting refers to scripts executed on a web server, handling tasks like database management, server configuration, and page generation. Client-Side Scripting, conversely, involves scripts that run in a user’s web browser, dealing with user interface elements and interactive features.
In Server-Side Scripting, scripts are processed on the server, and only the resulting output is sent to the client. In contrast, Client-Side Scripting involves scripts that are downloaded and run on the client’s machine, allowing for dynamic interaction without server communication.
Server-Side Scripting is used for creating customized web pages, handling form submissions, and accessing databases. Client-Side Scripting is utilized for enhancing user experience by enabling interactive content, real-time updates, and responsive web design.
Server-Side Scripting languages include PHP, Python, Ruby, and ASP.NET. Client-Side Scripting mainly involves JavaScript and frameworks like Angular, React, or Vue.js.
Security in Server-Side Scripting is crucial as it involves direct access to the server and databases, while in Client-Side Scripting, security focuses on preventing attacks like XSS (Cross-Site Scripting).
