Currently, I am involved in a create-react-app project. To update the deployment, all I do is run npm run build in my local github repository, generating a build folder within the project. Following that, I proceed to transfer the build folder into my company's server directory (which honestly, I have no idea how it was configured). Subsequently, the application deployment gets updated. What concerns me is that when I execute "npm run build" on a specific branch, the changes also seem to reflect on other branches when I switch between them. This has prompted me to question how this process actually functions. Does the build folder remain constant and carry over when switching branches, or does it adapt based on the active branch?
