When I use classes, when I don’t, what I do instead and why 9 years ago
" Usage of class is not bad. It definitely has its place. If you have some really “hot” code that’s a bottleneck for your application, then using class can really speed things up. But 99% of the time, that’s not the case. And I don’t see how classes and the added complexity of this is worth it for most cases (let’s not even get started with prototypal inheritance). I have yet to have a situation where I needed classes for performance. So I only use them for React components because that’s what you have to do if you need to use state/lifecycle methods (but maybe not in the future). "
Why would classes have any inherent performance benefits (and over what) ?
