Commits are operations that send the latest changes made in a code to the repository. It saves the changes made in a file or multiple sets of files in the version control system. The term commit mostly revolves around the permanent changes that are made and saved in a repository. Each and every commit allows the contributors to keep an account of the changes that are made by making a unique identifier or hash code. They come with a piece of unique specific information about the changes made, the date, the editor, and a small note telling the details of the changes. It is very similar to saving a file to a device, but commits bring an extra layer of documentation. They act as a tracking manual for the changes made to a particular set of data. You are able to roll back to the previous, unedited version of your data if any bug occurs using commits. They safeguard the integrity of data and allow the developers to track any changes in the data.


  1. How many commits can we make?

There is no number defined as to how many commits can be made. But you should commit after major modifications rather than for every minor change. It is worth noting that while there’s no strict limit, excessive commits can lead to noise in the version history.

  1. Do we need separate commits for every change?

It is not preferable to have commit for every minor change. You should make group-related changes to one commit so as to make it easier for the other contributors to track through. Every commit will denote a plausible and logical change in the data.

  1. Can commits be changed after being made?

Commits can be easily altered using the required set of commands, but you may face problems if the changes are made in a shared repository.
