Diff Arrays
Utility method to compute the difference between two arrays. AMD and CommonJS compatible; works in Node.js and the browser.
It's fork of array-difference that shows in the output if the
difference is on the left-hand side (lhs) or right-hand side (rhs).
Thanks Mike Pennisi for the original.
Installation
$ npm install diff-arrays
Example
var da = require('diff-arrays');
var left = [
'anyone@example.com',
'anytwo@example.com',
'anythre@example.com',
'anyfour@example.com'
];
var right = [
'anyfour@example.com',
'anyfive@example.com',
'anysix@example.com',
'anyseven@example.com'
];
var diff = da(left, right);
console.log(diff);
Outputs
{ lhs:
[ 'anyone@example.com',
'anytwo@example.com',
'anythre@example.com' ],
rhs:
[ 'anyfive@example.com',
'anysix@example.com',
'anyseven@example.com' ] }
