One line if/else in JavaScript

Question

I have some logic that switches(with and else/if) true/false with on/off but I would like to make is more condensed and not use a switch statement. Ideally the if/else would be converted into something that is one short line. Thank you!!!

var properties = {};
var IsItMuted = scope.slideshow.isMuted();
if (IsItMuted === true) {
    properties['Value'] = 'On';
} else {
    properties['Value'] = 'Off';
}       

Answer 1

You want a ternary operator:

properties['Value'] = (IsItMuted === true) ? 'On' : 'Off';

The ? : is called a ternary operator and acts just like an if/else when used in an expression.

Answer 2

You can likely replace your if/else logic with the following to give you a "one-liner"

properties['Value'] = scope.slideshow.isMuted() ? 'On' : 'Off';

see Conditional (ternary) Operator for more info

Answer 3

var properties = {"Value":scope.slideshow.isMuted() && "on" || "off"}

Answer 4

Combine all into one line.

You don't need to create empty object, it can have properties and if brevity is what you want don't need the isItMuted either

var properties = {Value : scope.slideshow.isMuted() ? 'On' : 'Off'};
