MDX

noun

MDX is a file format that lets you combine Markdown with JSX, JavaScript expressions, and import and export statements.

The product page is an MDX file that uses an interactive component.

MDX lets you write text and interface components in one file. MDX tooling compiles that file into a component for use in a website or application.

Which components and JavaScript a file can use depends on the project setup. The MDX documentation explains how the syntax and integration work.
