Nice solution!

The g means global which means check the entire string and don't just stop at the first number it finds.

Bitwise operators internally convert JavaScript numbers (doubles) to signed 32-Bit integers to perform their function; see the spec for the bitwise NOT operator and bitwise binary operators. 2,147,483,647 is the largest positive value a signed 32-Bit integer can take (see e.g. its Wikipedia article).

edits: Originally I said that their return value is a 32-Bit integer, which is true, but beside the point.

Very nice idea to start again the loop

Brilliant solution!!

Brilliant solution!! The initial statements for initialising and management of cases is really good. Congrats

Great idea reusing functions
