the new frontend talent starts his internship. He has used git but knows nothing about it. He only knows how to upload the code, regardless of the trunk branch. Today, the team leader briefly talked about trunk and branch;. I don"t know if he understood it. He asked me to create two folders, one is trunk and the other is branch;, which asked me to develop in branch to form a good habit. Then I pulled a project, which is in trunk and in branch. He told me to develop, update and submit in branch; update as soon as I come every day, and then submit it when I leave; my understanding is that branch is our current development environment, messing around in it. But I don"t quite understand the trunk folder, and I pulled the same project; but what"s the use? I do it in branch every day; whether it"s submit or update; I haven"t touched the project in that trunk; I"ve asked them once or twice that it"s easy, but I still don"t understand it.
