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 ]Returns the initial elements which both input arrays have in common

This library is compatible with Node.js, the Web and any style of module loader. It can be loaded anywhere, natively without transpilation.
Node.js:
const commonSequence = require('common-sequence')Within Node.js with ECMAScript Module support enabled:
