alt Hacker News> everything else inside an Electron app can be identically fast to a native application.
HTML layout and rendering is almost never as fast as GUIs like Qt. Also Electron apps usually use JavaScript which is slower than "fast" languages like C++/Rust/Kotlin/etc.
The reason people use Electron is because it's easy, especially if you have to have a website anyway. Slack is a great example of this. They already have a full website so it's kind of silly to redo the whole thing...
Unless AI makes it easy. We'll see I guess.
You are right about "almost never as fast as", but it is imperceptible to any human. We're talking about less than 100ms to render basically any typical UI, which then updates faster than 30fs. I said "identically fast"; I should have said "with respect to human perception".
