What’s funny about this comment is how detached from reality it is.
If you round, approximately zero users of Electron apps know how to do what you’re talking about, and yet they continue to successfully use Electron apps across a variety of platforms.
The fact that you have to finely manage your system’s memory is a you thing, not an Electron thing. The two are entirely orthogonal.
Memory is not a precious resource, no matter how much you want to live in a world where your obsessive compulsion to manage it is reasonable.
