Variables & Functions

Ternary Operator

A shorter way to write if...else statements. It has three parts:

let someVar = [the condition] ? [the value if true] : [the value if false];

It’s the equivalent of this.

let someVar;

if ([the condition]) {
	someVar = [the value if true];
} else {
	someVar = [the value if false];
}

Let’s say we wanted to define answer as num if num is greater than 10. If not, we’ll use 42.

let num = 0;
let answer = num > 10 ? num : 42;
