I played with mdn-cli which was a neat cli that queries duckduckgo for the first mdn result and parses it to markdown. I then passed that through a parser to make it pretty, and then integrated it with my editor for getting fast documentation without too much context switching.
My biggest gripe was the lag to request ddg and then mdn and then parse it and pipe it. I wanted something simpler like `man` for mdn. Now i imagine having the documentation already in md and keeping it local, i'm a step closer and it'll be more powerful with tools like fzf, ripgrep, and mdcat.
Gotta check if there's already a search tool for MD that weighs heading levels, or code blocks, bold text, etc
