In JavaScript, you can represent a number is an actual number (ex. 42), or as a string (ex. '42').
If you were to use a strict comparison to compare the two, it would fail because they’re two different types of objects.
var num1 = 42; var num2 = '42'; if (num1 === num2) { console.log(true); } else { console.log(false); } // Will log `false`  Today, let’s look at three different ways to convert a string into a number.
