Add numeric separator

Why is this refactoring helpful?

Long numbers can be hard to read, especially when they are in binary or hexadecimal formats. Separators break up a long number into more readable segments.

What do I need to consider?

Numeric separators are an ES2021 feature. They are supported on all modern browsers and on Node 12.5+, but for older browsers and Node versions transpilation might be required (compatibility).
