Will bypass a few validations if server accepts as param from client:

Number(Infinity) -> Infinity

Infinity < 5000 -> will return false even though Infinity is acting as a 0 here

This is probably a good opportunity to have a heated discussion over parseInt() vs Number() since parseInt('Infinity') yields NaN. I know people prefer Number() for reasons but in this case it reveals the weakness of using basically a typecast with implicit language semantics for interpreting string inputs.

parseFloat('Infinity'), JSON.parse('1e1024'), or parseFloat('1e1024') work just fine ;-)
