I run into a lot of cases where I would like to use the condition of a ternary as the actual value of its output. Is there a way to do this without having to say the condition again?
var thing = veryCoolThingExistsButItsNameIsVeryLong ? veryCoolThingExistsButItsNameIsVeryLong : otherThing;
What I want is something that looks more like this:
var thing = veryCoolThingExists?otherThing; where
thing is assigned
otherThing only if
veryCoolThingExists doesn’t exist.
You can use the logical OR operator,
var thing = veryCoolThingExistsButItsNameIsVeryLong || otherThing;
which returns the first value if it’s truthy or the second if not.
