A hashing function which returns integers with a possible max value
npm install hash-indexA function which will always return the same output given the same
input. The output is an integer in the range 0..n. By default n is
infinity-1, but another max value can be provided as an optional 2nd
argument.
The output is not guaranteed to be unique - only to be predictable based
on the input.
``
npm install hash-index
`js
var hasher = require('hash-index')
// same input => same output
hasher('bob') // => 79268366047899
hasher('alice') // => 90345298322240
hasher('bob') // => 79268366047899
hasher('alice') // => 90345298322240
`
Using the optional 2nd argument, you can supply an upper limit for the
returned hash value:
`js`
hasher('bob', 100) // => 99
hasher('alice', 100) // => 40
hasher('bob', 100) // => 99
hasher('alice', 100) // => 40
If no max value is given, infinity-1 is used as the max value.
If max is less than 1 then NaN will be returned.
The input have to be either a non-empty string, a number or a non-empty
array. If not, NaN` will be returned.
