What's the output?
let a = 3;
let b = new Number(3);
let c = 3;
console.log(a == b);
console.log(a === b);
console.log(b === c);You missed this one before
new Number() is a built-in function constructor. Although it looks like a number, it's not really a number: it has a bunch of extra features and is an object.
When we use the == operator (Equality operator), it only checks whether it has the same value. They both have the value of 3, so it returns true.
However, when we use the === operator (Strict equality operator), both value and type should be the same. It's not: new Number() is not a number, it's an object. Both return false.
