eslint-plugin-max-comments-per-function

Rule to limit the number of comments in a function body.

Experimental. A dumb heuristic to reduce line noise. Comments as percentage of line count might be a smarter choice.

Based on max-lines-per-function from the ESLint core rules, originally by Pete Ward. LICENSE (MIT) preserved.
