This is expected. You can delete .map files from the build output if you want to disable it, although you'll get console warnings about them missing.

There is no harm in leaving them in though in my opinion. Client code is already available to the user’s machine so there’s no secrets in it.

scripts: {
  "build": "GENERATE_SOURCEMAP=false react-scripts build"
}
