This is a silly list. What? You really think document.getElementById is going to be faster than querySelector("#foo")? You really think there is a meaningful difference between other methods of adding event handlers, other than it being way hackier to add more than one with the other methods?

I have no idea what your objection to "this" is. Object Oriented code can be bad sometimes but so can procedural code.

This person has a weird unjustified objection to querySelector.

I remembered this same conversation from 8 months ago where I pointed out that parsing something like '#foo' is NOT slow, he argued against it, 5 people pointed out the same thing, and he was not receptive to that feedback, etc.

Performance is hard; optimizing the wrong thing is also a problem ...

I guess you ignored this from that thread: https://news.ycombinator.com/item?id=24057163

What precisely do you think a microbenchmark taken out of context is going to prove?

That a 250,000x performance difference is a very large gap. It’s the difference between walking 1 foot or 48 miles.

Or the difference between walking 1 femtometer or a quarter of a nanometer in a day where you're planning to hike 10km. And that's assuming the relative difference holds to the same degree in a real app, which seems unlikely.

P.s. i also didn't get that level of difference when i tried to run the microbenchmark but i didn't try very hard.
