Numbers once they get to a certain size can be difficult to read. Reasonably enough, seeing 10000033838300 on a screen can be difficult for anyone. Luckily, JS introduced a cool way to make numbers a bit easier on the eyes. This being the numeric separator.
const testNumber = 1_000_000;
console.log(testNumber);
// '1000000'Easy, and so much better! Now when you’re writing numbers in JS keep this handy tidbit close. Your code will look cleaner, and be much easier for others to come into an understanding with.
