// ternary operators are frequently used as a shorter cleaner if statement
// condition ? exprIfTrue : exprIfFalse

let age = 15;
let canDrive = age >= 16 ? 'yes' : 'no';
// canDrive will be 'no'
// the condition will be age > 16 which is false so canDrive will equal exprIfFalse

// this ternary is the same as this if else statement
let age = 15;
let canDrive;
if (age >= 16) {
    canDrive = 'yes';
} else {
    canDrive = 'no';
}

// canDrive will be 'no' because 15 is less than 16
