When working with large numbers it can be hard to read them out, try to read this value for example:
const value = 100000000;
10_000. The feature works in recent versions of modern browsers as well as Node.js.
When we apply this to the top example we can easily read out the value:
const value = 100_000_000;
The numeric separator also works on octal, hex, and binary numbers:
const octalValue = 0o32_12; const hexValue = 0xff_55_00; const binaryValue = 0b1010_1011_1111;
Now let's keep those numbers easy to read!
