How to push changes from local branch A to remote branch B?

Question

git

I worked on a computer on branch A, but I was blind and changes had to be made on branch B.
Can I somehow switch to a branch with the transfer of local changes, or push from local A to remote B?

Answer 1

1) Commit your changes to branch A, checkout to branch B, shard your commit to branch B and push it

2) Easier. Move to branch B locally, merge changes from branch A into it and push it.
The second option only works if there is nothing extra in branch A that you should not push to the server
