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.

> 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:

> a.commonSequence([ 1, 2, 3 ], [ 1, 2, 4 ])
[ 1, 2 ]

commonSequence(a, b) ⇒ Array

Returns the initial elements which both input arrays have in common

Kind: Exported function
