Returns a regex-compatible range from two numbers, min and max. Inspired by jonschlinkert/to-regex-range.
That's a good question. You normally would write something like if ($x > $min && $x < $max) { ... }, right?
Say you want to build a glob like function yourself.
If your glob would support syntax like foo/{1..5}.md and you plan to do the matching using a regex pattern.. Well, this library can convert 1..5 to a regex.
