What is your favourite function()?

I think mine would be json_encode(). I think it's so cool that a single function can make your data understood by other machines. (I know other machines can interpret different kinds of data, but c'mon...)

How about you? What's your favourite function?

var moment = require('moment');

explain_fork_or_die();

Based on usage it's probably console.log() or var_dump().

At the moment I'm enjoying some JavaScript array methods - filter, map, reduce.

var_dump (); die ()!!!

[Tiago Marques]

I usually do like:
die(var_dump());

[ｅｎｄａｎ]

I stopped doing this simply because I can't do it if I dump multiple variables at once.

var_dump($res);
var_dump($res2);
die();

[Alex Lohr]

But you could do die(var_dump($res, $res2));, couldn't you?

[Tiago Marques]

You can

[ｅｎｄａｎ]

Really? Wow, #TIL!

[Tiago Marques]

Yeah, just like console.log(var1, var2) in JS

typeof(arg);

surprisingly useful

random() functions, there is so much more behind them then we usually think. I can talk hours about entropy and sources, techniques, pseudo algorithms and how can it improve almost any software product.

[ｅｎｄａｎ]

Improve in what way?

[IsaacLeimgruber]

In the way of randomized algorithms

[Adrian B.G.]

As in, some product features can be improved using random (shuffle or generate things), most basic example is chose new 5 news headlines to see from the top 100 articles to an user, each x seconds/page views.

$("");

Because it took me almost half a year to realize that it's a function, not a language construct.

[Jishnu Vasanth]

Arrow function 🤓. this has never been easier.

[essic]

mine is fmap ...
fmap :: (a -> b) -> F a -> F b
with F being a Functor :-)

I find this one, truly comforting for some reason.

[Bertil Muth]

I like map.put and map.get. Maps/Dictionaries are incredibly useful data structures that we tend to take for granted nowadays.

Don't know if it's only a function, but ajax in Javascript is something else: the whole idea of a function connecting asynchronously to a server and retrieving data without the need of recharge the entire page is amazing.
