When creating a hash to store functio results against, the callback is omitted from the hash and an optional hash function can be used. +If no hash function is specified, the first argument is used as a hash key, which may work reasonably if it is a string or a data type that converts to a distinct string. Note that objects and arrays will not behave reasonably. Neither will cases where the other arguments are significant. In such cases, specify your own hash function. + The cache of results is exposed as the `memo` property of the function returned by `memoize`. |
