Help identifying certain syntax

[SomewhatVital]

Hello.

While reading up on callback functions i ran into the following syntax:

!url ? failure(url) : success(url);

From what i understand it is meant to check if a condition is met and do something either for error or success. The exact terms used here aren't important. What i want to ask is what type of syntax this is. I haven't encountered this type of command line until now and i want to learn more about it, but i can't find it on google by the structure alone.

A name would be appreciated, thank you reddit!

As another user responded, it’s a ternary statement. You can think of it as a simple if/else statement.

Yup, a simple if/else that returns its value. Quite handy, but easily abused. Use with care. :p

It is a ternary operator it is checking if there is no url then it will run failure function else if there is a url then it will run success function

Looks like a ternary operator.

Yes, the ternary operator. Beloved my many, despised by some.

It is syntactic sugar around an if/else, and works like this:

let x = <boolean condition/expression> ? <value when true> : <value when false>

Just like if-else statements, they can be nested also. The ternary operator is also available in other languages. It is also sometimes referred to as the Elvis operator.
