Ternary if?then:else

gotacha. i’ve only ever heard them called ternaries. maybe i’m old. maybe i’m too young. definitely one of the two

@QuazarOmega@lemy.lol

It specifically refers to this shorthand ?: that works like this:

$value = $thing_that_could_be_truthy ?: 'fallback value';

# same as

$value = $thing_that_could_be_truthy ? $thing_that_could_be_truthy : 'fallback value';

The condition is also the value if it is truthy

@dev_null@lemmy.ml

It’s a shorthand for writing this:

variable = if (input != null) input else default

This is equivalent:

variable = input ?: default

The answers confusing it with the ternary operator are wrong.
