What does this code mean?

Question

var num = 0;
console.log(num?"fulse":"true")

Answer 1

İnline if statement

var x0 = 0;
console.log(x0===0?true:false);//true
var x1 = 1;
console.log(x1===1?true:false);//true
var x2 = 0;
console.log(x2?true:false);//false
var x3 = 1;
console.log(x3?true:false);//true
var x4 = 0;
console.log(x4?"✔":"✘");//✘ means false

var x5 = 1;
console.log(x5?"✔":"✘");//✔ means true

//Thank you for your help guys ☺

Answer 2

It's called a ternary operator,

0 for false
1 for true

var num = 0
|_____________
⬇️ ⬇️
(false?"false":"true")

The output is just a great way to confuse yourself I wouldn't recommend using these strings if your learning. use...

(num?"condition is true":"condition is false");

Answer 3

That is an "inline" if. It checks the condition, and returns either value.

var num = 0; // 0 is the int version of false, anything bigger is true
console.log(num?"false":"true"); // If num is true (which it isn't), return the string "false" to console.log() otherwise "true"
