I love editing in VS Code, but I couldn’t get my MDX files to wrap on a specific column width without affecting all my other files. I want my MDX files to wrap because that’s how I write blog posts, but I don’t want any of my JS files to wrap because it makes it much harder to read. After doing some research, I was able to piece together a solution.

Paste this code in your settings.json file

    "[mdx]": {
        "editor.wordWrap": "wordWrapColumn",
        "editor.quickSuggestions": false,
        "editor.wordWrapColumn": 80,
    },

If you use markdown instead of MDX, change the [mdx] to [Markdown].
