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

Edited by Aimie Carlson || By Harlon Moss || Published on February 17, 2024
Server-side scripting involves scripts executed on the server, affecting website functionality, while client-side scripting runs in the user's browser, affecting interface and user experience.

Key Differences

Server-side scripting is processed on the web server, generating dynamic web pages before they are sent to the client. Client-side scripting runs directly in the user's browser, modifying content after the page is loaded.
Server-side scripting can access server resources and databases, performing complex operations like user authentication. Conversely, client-side scripting mainly deals with interface elements, like form validation and interactive features.
Server-side scripting languages include PHP, Python, and Ruby, which are used to build the backend of websites. Client-side scripting primarily uses JavaScript to create dynamic and interactive user interfaces.
Server-side scripting ensures that the source code remains hidden from the user, enhancing security. On the other hand, client-side scripting code is visible to users, which can pose security risks if not properly managed.
Server-side scripting is essential for creating web applications that require frequent server interaction. Client-side scripting is ideal for creating responsive and interactive web pages that require minimal server interaction.
