js ternary

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"

//ternary operator example:
var isOpen = true; //try changing isOpen to false
var welcomeMessage  = isOpen ? "We are open, come on in." : "Sorry, we are closed.";

condition ? exprIfTrue : exprIfFalse

function 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 elvisLives = Math.PI > 4 ? "Sip" : "Nop";

var variable = (condition) ? (true block) : ((condition2) ? (true block2) : (else block2))

        
            
        
     var age = 19;
var canDrive = age > 16 ? 'yes' : 'no';

condition ? doThisIfTrue : doThisIfFalse

1 > 2 ? console.log(true) : console.log(false)
// returns false
