common-sequence


common-sequence

Returns an array containing the initial elements which both input arrays have in common.

A common use-case for this is discovering common ancestors between two file paths.

``js
> commonSequence = require('common-sequence');

> pathA = '/Users/lloyd/Documents/75lb/dmd'.split('/');
> pathB = '/Users/lloyd/Documents/75lb/array-tools'.split('/');

> commonSequence(pathA, pathB).join('/');
'/Users/lloyd/Documents/75lb'
`

or a more trivial example:
`js
> a.commonSequence([ 1, 2, 3 ], [ 1, 2, 4 ])
[ 1, 2 ]
`

$3
