### 8. Call `Menu.setApplicationMenu(null)` when you do not need a default menu
Electron will set a default menu on startup with some standard entries. But there are reasons your application might want to change that and it will benefit startup performance.
#### Why?
If you build your own menu or use a frameless window without native menu, you should tell Electron early enough to not setup the default menu.
#### How?
Call `Menu.setApplicationMenu(null)` before `app.on("ready")`. This will prevent Electron from setting a default menu. See also https://github.com/electron/electron/issues/35512 for a related discussion.
