Markdown files tend to get really long as you begin authoring them and sometimes separating into pages just isn't enough. mdx-js enables you to import Markdown files then render them inside of other Markdown files as JSX so you can easily separate files into sections and keep everything organized.
Instructor: [00:00] I have a page in my index.md file in my pages directory. I am going to create a section. I am going to create a directory called sections and a file called intro.md with an h2 welcome and some content like, "Isn't discreet?"
[00:17] What I can do now is go back into my pages in my index.md. I can import intro from the relative path as upper directory into my sections. You could name sections whatever you want or this directory whatever you want, and /intro.md.
[00:36] A quick tip here is since this is not valid md, if you install the MDX extension in VS code, I can change the language mode to MDX. Now, this will look much nicer, then I destroy the JSX of intro. Close that all. Hit save, and you'll see I have an index.md, which is importing this intro.md into itself and rendering up.
