Being forced to read the documentation carefully every time you call the method is really bad UX though. And the approach in the article (let ms = 5; sleep(ms);) can be wrong. Maybe the method is actually taking microseconds not milliseconds and this causes a bug. I can also imagine linters (or other humans) fighting this style, since it’s longer, and something you have to actively do every time you call the method. Putting the units in the method name (when you can) fixes all of this. Sleep_milliseconds(5) is impossible to misuse or leave undocumented.
