difference

Subtract one list from another

Installation

$ npm install @f/difference

var difference = require('@f/difference')

difference([1, 2, 3], [2, 3, 4]) // -> [1]
difference([1, 2], [3, 4])       // -> [1, 2]

a - The list to be subtracted from
b - The list to subtract from a
getKey - Optional key function for the items of both lists. If not passed, a much slower algorithm is used. It is highly recommended that you pass getKey.

Returns: The result of filtering the items in list a to contain only items not found in list b.
