What will happen to the merged branch in git?

Question

git

Hello.
There are two development branches in my project. (br1 and br2)
I need to merge the br2 branch with my br1 so that nothing happens to the br2 branch and the second developer continues to work in it.
Tell me, if I use merge with a recursive strategy, will I get what I want or not?

Answer 1

You can do
git checkout br1
git merge br2
Changes from br2 will go into br1. br2 will not change in any way.
