Wouldn't be great if there is a feature which check if a function has been properly commented. (Feature request)

Hi Codemetrics is quite a good tools and helps manage a clean codebase., but people still have a habbit of skipping comments and then regretting it later. If there was an implementation of whether one has commented of not and comment score would be good.

There's no real way for code to determine what a good comment is. A substantial amount of developers can't write good comments to begin with.

If you force developers to write comments in their functions, you might end up with bad commenting like this: (taken from here):

function hashIt(data) {
  // The hash
  let hash = 0;

  // Length of string
  const length = data.length;

  // Loop through every character in data
  for (let i = 0; i < length; i++) {
    // Get character code.
    const char = data.charCodeAt(i);
    // Make the hash
    hash = (hash << 5) - hash + char;
    // Convert to 32-bit integer
    hash &= hash;
  }
}

Looking at something like JSDoc/Javadoc/whateverdoc might be more useful but sometimes even that is just noise. I don't think there is a proper way to mandate comments across all languages (and sometimes even within one langauge), just because so many different code styles would support useful comments in different ways.
