Learn how to show a time indicator on the screen that updates in real-time. Ideal for making clocks, chronometers or countdown, the process is the same and uses Date and setInterval.

Learn how to rename branches in Git the right way. According to the documentation, to rename a local branch in git there is only one command: git branch -m "new-name". But learn the right convention.

Learn how to clone JavaScript objects efficiently, be it a shallow copy or a deep clone of the object.
