Client-side scripting

Client-side scripting refers to the use of JavaScript on a website. This can be through manipulating content, or responding to user interaction.

JavaScript is run through a JavaScript engine, which combines native code, for processes such as sorting an array, alongside JavaScript code. This allows JavaScript to be surprisingly performant.

Chromium (and Google Chrome) uses the V8 engine, which is written in C++ and can run JavaScript and WebAssembly code. This is open source, and also used by React Native for hybrid mobile app development.
