Did you just commit some changes and forget to delete that console.log('test') statement? Use git commit with --amend to edit the previous commit and --no-edit to keep the previous commit message.

# 1. Delete the console.log

# 2. Stage the changes
git add my-file.js

# 3. Commit by updating the previous commit
git commit --amend --no-edit

Do this for local commits only. Don't amend commits that you already pushed.
