Cursor, GitHub Copilot and the less mentioned Windsurf editor are great!

💡 Here is another alternative to overview an open source framework: DeepWiki by the team at Cognition

It is not an editor, but if you just replace the "github" in the repo URL with "deepwiki" it will show a very nice documentation with diagrams.

Here is the DeepWiki for Eric Smith's DataTable LWC:

NOTE: I haven't validated the documentation that DeepWiki AI generates but so far it looks very good.
