how to use ternary operator in javascript

condition ? ifTrue : ifFalse//ternary operator syntax and usage:
condition ? doThisIfTrue : doThisIfFalse

//Simple example:
let num1 = 1;
let num2 = 2;
num1 < num2 ? console.log("True") : console.log("False");
// => "True"

//Reverse it with greater than ( > ):
num1 > num2 ? console.log("True") : console.log("False");
// => "False"var variable;
if (condition)
  variable = "something";
else
  variable = "something else";

//is the same as:

var variable = condition ? "something" : "something else";condition ? doThisIfTrue : doThisIfFalse

1 > 2 ? console.log(true) : console.log(false)
// returns falsefunction example(…) {
    return condition1 ? value1
         : condition2 ? value2
         : condition3 ? value3
         : value4;
}

// Equivalent to:

function example(…) {
    if (condition1) { return value1; }
    else if (condition2) { return value2; }
    else if (condition3) { return value3; }
    else { return value4; }
}
var age = 26;
var beverage = (age >= 21) ? "Beer" : "Juice";
console.log(beverage); // "Beer"
