JavaScript Adding Booleans

Question

console.log(true+true); //2
console.log(typeof(true+true)); //number
console.log(isNaN(true+true)); //false

Why is adding together 2 boolean types

Answer 1

Javascript is loosely typed, and it automatically converts things into other things to fit the situation. That's why you can do var x without defining it as an int or bool
