A JSX file may also be a JavaScript ( .JS ) file written using JSX syntax . It contains code that is most likely part of a single-page or mobile application. JSX files can be opened in any text editor, but are meant to be opened in source code editors.
More Information
JSX, also known as JavaScript XML, is an extension to the JavaScript programming language. Developers use JSX syntax when developing user interfaces and other application components using React, an open source JavaScript library developed and maintained by Facebook.
For the most part, developers use React and JSX to develop single-page or mobile applications. When a developer saves a JavaScript file written using JSX syntax, they usually (but not always) save the file as a JSX file.
How to open a JSX file
Because JSX files are plain text files, you can open them in any text editor, such as Microsoft Notepad (Windows) or Apple TextEdit (Mac). However, if you plan to edit a JSX file, you should open it in a source code editor, such as Microsoft Visual Studio (Windows) or Github Atom (cross-platform). Source code editors provide helpful editing tools and highlight JSX syntax correctly.
