Electron is not exactly an epitome of a resource efficient framework either. If I was to compare efficiency, I’d choose a native baseline, such as the X window system or WinAPI. Granted, these APIs are low level and not as rich in features. Typically, the user calls some sort of “mark as dirty” function to mark a region of the window to be updated on the next refresh cycle, thus not wasting resources on portions of the screen that were not touched.
