We're discussing one right now. VSCode is an electron-based application, isn't overly-bloated, and starts up quickly. I switch between IJ and VSC every day and VSC is significantly faster, including startup. But, even if it _was_ slower on startup, that would be a tradeoff I'd be happy with if it was faster or more functional normally. I restart my computer maybe once a week, I'd be fine to wait another couple seconds.
VSCode is better than many, but I do think it counts as bloated, has reasonably high recommended machine requirements, and performs more poorly than I would expect of such an application.
It does perform better than IJ and the like, but that's a bit of damning with faint praise.
I don't comment beyond that on it as I don't use it more than I have to (for reasons unrelated to it being Electron-based) and want to avoid Speaking Of That I Know Not. I was speaking about Electron more generally.
