Making calculations with longer numbers? You can improve readability by using underscores (_) in numeric primitives:
// Hard to read:
Math.floor(Math.random() * 1000000); // 337083
// Better
Math.floor(Math.random() * 1_000_000); // 337083
1_000_000 === 1000000 // true
The underscore doesn't have to be placed where a comma would go - it can be used anywhere in the number except at the very beginning or end. Just a small way to improve your code and prevent errors!
