JSX files exist as 2 different types. Please find information about each of them below.
Type 1: ExtendScript Script File

A file with .jsx extension is a script written in ExtendScript language. ExtendScript extends JavaScript functionality for Adobe Creative Suite plug-ins. JSX files are used for Adobe applications like Photoshop, After Effects and InDesign plug-ins. .jsxbin is the binary version of .jsx files. JSX or JavaScript XML files are executable; opens with After Effects on Windows 10.
ExtendScript supports additional functions that JavaScript does not. So .jsx files are not always JavaScript. After Effects scripts use .jsx extension too. ExtendScript Toolkit exports JSX scripts in binary .jsxbin format. Binary JSX files may not work with all After Effects script features.
After Effects scripts must have .jsx extension to be recognized. Any UTF-8 encoded text file with .jsx extension is an ExtendScript. By default, scripts cannot write files or communicate over network. This can be activated in preferences.

JSX files contain JavaScript and XML-like code to define React components. These .jsx files allow writing components in HTML-like syntax instead of JavaScript objects. One can open JSX files in any text editor. However, source code editors better highlight JSX syntax.
React apps usually have a .js entry point by convention. But it could be .jsx. Using .jsx for all components shows file types across a large project. However, .js works fine too.
JSX allows HTML inside JavaScript, not vice versa. Developers often use JSX for single-page or mobile apps. They commonly save JSX-written files as .jsx for clarity. Various programs open JSX files. One can also drag a JSX file into a browser to display it.
JSX differs from HTML by its file extension. JSX extends JavaScript syntax, allowing HTML-like code to conveniently create React UI parts. Alternatively, .js files need functions to manipulate React elements. So JSX enables an intuitive way to work with React components.
