  barrel-optimization is a main directory that collects 2 subdirectories: basic and mui.
  At the top level, 'basic' comprises 2 contained folders: app, node_modules.
  Within directory hierarchy 'basic → app', Within 'app', you'll find 1 contained folders for code structure.
  In nested path 'basic → app → mixed-barrel-imports', Inside 'mixed-barrel-imports', you'll find it has no content.
  Within directory hierarchy 'basic / node_modules', 'node_modules' possesses 2 packages: mixed-lib, my-lib.
  At level 3, in directory path 'basic → node_modules → mixed-lib', The 'mixed-lib' data structure has no content.
  Within directory hierarchy 'basic > node_modules > my-lib', 'my-lib' holds 1 folders: client.
  Within directory hierarchy 'basic / node_modules / my-lib / client', The 'client' compartment remains unused.
  In the root directory, 'mui' comprises 1 contained folders: app.
  Within directory hierarchy 'mui > app', 'app' stands empty.
