Hey people who know about browser implementations, what does a browser do when it comes across code like this? for (let i = 0; i < 100; i++) { const x = () => {} x() } Does it allocate memory for a new function every time or is it more fancy?

Definitely optimizations devs shouldn't worry about. There are some plugins that do some cool optimizations, like this one for example: https://babeljs.io/docs/en/babel-plugin-transform-react-constant-elements … Not sure whether there are any optimizations in the syntax/language feature plugins though.
