{{alias}}( fcn[, hashFunction] )
|
||
|
|
Returns a memoized function.
|
||
|
|
|
||
|
|
The function does not set the `length` property of the returned function.
|
||
|
|
Accordingly, the returned function `length` is always zero.
|
||
|
|
|
||
|
|
The evaluation context is always `null`.
|
||
|
|
|
||
|
|
The function serializes provided arguments as a string and stores results
|
||
|
|
using the string as an identifier. To use a custom hash function, provide a
|
||
|
|
hash function argument.
|
||
|
|
|
||
|
|

Function to map a set of arguments to a single value identifying that
