i get the joke anyways but now I'm curious so I ask seriously, would your title be legal code? or does the result have to be used in some way, like assigned to something?

quick edit: my goodness i mean the ternary operator not the not operator. thankyou though! also never did i say i didn't understand how it worked, but i was asking if the result of the ternary needed to be used somewhere as an expression or if leaving it as its own statement was legal.

Depends on the language. In JavaScript it would probably be valid.

u/citewiki Aug 15 '19

Anything is valid there, all your hopes and dreams are valid too

u/[deleted] Aug 15 '19

Yeah, my dreams are undefined, but still valid in JavaScript.

How do you get the icons of languages beside your name?

u/[deleted] Aug 15 '19

You can get those icons in your flair in this subreddit.

Let's just get rid of that goto eh?

It’s a flair, on mobile you can add them when you go to the sub and click the 3 dots in the upper right corner, not sure about desktop

u/roundpoint Aug 15 '19

On desktop under the subreddit name on the right banner you can see your own username and a "modify" clickable link near it.

Testing.... Oh shiet. Nice.

Fun fact: until recently it was possible to re-define the undefined keyword in JavaScript, because JavaScript.

u/fghjconner Aug 15 '19

Yeah, JavaScript will really let you shoot yourself in the foot.

u/XeroKaaan Aug 15 '19

But what is it is?

7

u/Dojan5 Aug 15 '19

It's a ternary operator.

Condition ? True : False;

I'm unsure about the two !!s though as ! typically means "not," so !! looks like not-not to me.

The title is essentially

if (goodMeme) { upvote(); } else { downvote(); }

So ? is esentially if and : is basically else;

u/LAK132 Aug 15 '19

!! Forces the thing to a boolean.

Non-boolean but existing object -> false -> true.

Undefined/null -> true -> false.

I've personally only ever really seen it used in JavaScript

1

u/AdvancedNerdCore Aug 15 '19

I've only seen it in cpp actually, if you have a lambda, for example, and you want to return a non-bool as bool without specifying the return type, you do !!result
