- Use `String.prototype.padStart()` to fill the beginning of the string with the `mask` character up to the original length.
|
||||
- If `num` is negative, the unmasked characters will be at the start of the string.
|
||||
- Omit the second argument, `num`, to keep a default of `4` characters unmasked.
|
||||
- Omit the third argument, `mask`, to use a default character of `'*'` for the mask.
