Suppose you're dealing with big numbers in JavaScript, you might know that they're becoming harder to read with every digit. Look at 123456789 – how many millions is that? I don't know! 🤷‍♂️

To solve this readability issue JavaScript implements numeric separators.

// Make large numbers more readable with numeric separators

// 1234456789.01

I was aware that the language addition is around the corner, but surprisingly, I just realized, they're cross-browser-supported these days! 🎉
