About "TL;DR" in the article as the title

Just a question about this fixed phrase at (https://github.com/nodejs/nodejs.org/blob/master/locale/en/docs/guides/dont-block-the-event-loop.md#tl-dr), because this phrase explains the process of Nodejs in the event and how to improve the speed of Nodejs' work.

I don't know why "TL;DR" for this phrase? Why does it mean "Too Long Didn't Read"？

So IMO the title should be something like "What to notice for improvement of efficiency for Nodejs in the event loop?"

@nodejs/website：What do you think of this？

An alternative title might be "Executive summary" or "Abstract" or similar.

Yeah, it basically means "Summary".
