I think it's standard for juniors to think comments just need to rephrase code. Commits titles are just comments (about changes)

    // if ID exists in commits
    if (commits.has(id)) {

Big sigh every time I see this, especially if the code is "well-commented"

    // if ID exists in commits
    if (commits.has(id)) {
      // make no changes
      return
    }

    // add ID to commits
    commits.add(id)

    // log ID to console
    console.log(id)

On the other hand, LOCs through the roof, 10x developer right here.
