Electron is garbage and just an exercise in providing a bad user experience to people for the sake of making front-end developers happy since they're the ones making them. The end result is bloated applications that are slow and use way too much system resources. VS Code used to use a significant portion (>10%) of the CPU just to draw a blinking cursor.
