<a name="module_common-sequence"></a>

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 ]

<a name="exp_module_common-sequence--commonSequence"></a>

commonSequence(a, b) ⇒ <code>Array</code> ⏏

Returns the initial elements which both input arrays have in common

Kind: Exported function

Load anywhere

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:

js
const commonSequence = require('common-sequence')

Within Node.js with ECMAScript Module support enabled:

js
import commonSequence from 'common-sequence'

Within an modern browser ECMAScript Module:

js
import commonSequence from './node_modules/common-sequence/index.mjs'

Old browser (adds window.commonSequence):

html
<script nomodule src="./node_modules/common-sequence/dist/index.js"></script>
