What are the great function/method/etc. names in popular libs/languages?

Naming things is hard, but what are the ones that have stood out to you as great choices that have stood the test of time?

I really like PHP's explode and implode couple. It's String.split and String.join for those who don't know.

I always thought it was kind of brilliant of the react team to hijack the reader’s brain to create a fake protected member by naming it _SECRET_DOM_DO_NOT_USE_OR_YOU_WILL_BE_FIRED

Android's UserManager class has something called isUserAGoat().

Here's an interesting discussion on it 😁

Not sure if this counts, but PHP's T_PAAMAYIM_NEKUDOTAYIM parser token is pretty rad yet savage :D

Damn, I was going to post this when I saw this thread ;)

The start of my journey as a programmer is a peculiar one in that regard.

As a non-native English speaker, when I started to code, a long time ago, I simply didn't understand anything. In fact, I thought that most reserved word of any language were just that: some "random strings" with no meaning outside of the programming language. It's later, when I had learned English that I got some Ah ah! moment.

Obviously for an English speaker: "if, case, switch, while, random" are just normal words. It wasn't for me. (I started to play around with code when I was a child, under MS-DOS 6)

So, talking about some great choices, my biggest and relatively recent "Ah ah! moment" has been with

Math.ceil
Math.floor

I could never remember which one would round up and which one would round down.
Until a day like any other day, my brain said: "hey, wait a minute: isn't "floor", because the floor is low and "ceil(ing)" is up?" Awesome. XD

I really like the convention to name mixins with-something in react and Vue. Often this feels very elegant. Like with-captcha.js or with-user.js. There couldn't be any naming that feels any smoother 😍

A common problem in PHP (maybe in some other langs too) is the way to move between dates and get the incorrect value, for example when you decrease or increase a month(s):

>>> (new \DateTime('2017-01-31'))->add(new \DateInterval('P1M'))->format('Y-m-d')
=> "2017-03-03"

Carbon a good library offers some methods to avoid this behaivor and their names are really good:

>>> (new Carbon('2017-01-31'))->addMonthNoOverflow()->format('Y-m-d')
=> "2017-02-28"

If you wanna get the calculation with this behaivor, no problem:

>>> (new Carbon('2017-01-31'))->addMonthWithOverflow()->format('Y-m-d')
=> "2017-03-03"

Other methods are: createMidnightDate, localeHasDiffOneDayWords, createSafe...

Maybe in Elm, not only because it's descriptive (Maybe it has a value, and Maybe it doesn't), but when it doesn't have a value, instead of null or undefined or whatever, it's Nothing.

Which makes me think of Nathan Explosion whenever I use it.
