If-else statements are pretty straightforward, but there’s a shorter way to write them:

var isEven = true;

isEven ? console.log(2) : console.log(1);

// 2

Syntax

condition ? firstExpression : secondExpression;

Ternary operators are easy to understand. It first evaluates if the condition is met. firstExpression is executed if the result is true and secondExpression if false.

Conditional Assignments

One common use case for ternary operators is conditional assignments. You can assign values depending on a specific condition:

var pokemon = 151;

var title = pokemon < 152 ? "noob" : "master";

// "noob"
