function - Javascript: Is there a use case for ever changing the arguments array -


i listening douglas crockford's infamous javascript video series (https://www.youtube.com/watch?v=ya4uhuxnygm) , made statement being careful not change the 'arguments' array parameter avoid "weird" things happening.

so made me curious: there every reason might want this? couldn't think of 1 other maybe self-modifying code trickery obfuscation perhaps.
