Here are some numbers...

When we show these to users we use separators

programming languages involve many kinds of numbers that you type and the language parses

let a = 1234121,
    b = 0x010101,
    c = 0xF,
    d = 0b1111

Numeric Separators provide a language separator so that your code can benefit from the same idea

let a = 1_234_121,
    d = 0b1111_1111
