Git merging the feature branch from the master branch will be helpful while you are working with the feature branch and your parent master/main branch is updated with new changes.
You can take the master branch changes to your feature branch by running a few commands to update your local feature with the same as the master.
I hope your main parent branch name is master. If your main branch name is production, replace the master word with production at end of commands 1 and 4.
git checkout master
git checkout feature/my-feature-branch (your branch name)
git merge --no-ff master
By running the above 5 commands in Git updated your local feature branch the same as the master branch.
This way you can always update your feature branch with the parent branch and you do not have any conflict error while pushing the code to the master.
