Array.prototype.dig and Array.prototype.digLast

The find and seek can only return an item of array. But the dig returns the value returned by your callback function if it is not undefined.

Usage

import 'https://better-js.fenz.land/src/array-prototype/finding.js';

const obj= { bar:null, baz:0, }

[ 'foo', 'bar', 'baz', 'qux' ].dig( x=> obj[x], );     // null
[ 'foo', 'bar', 'baz', 'qux' ].digLast( x=> obj[x], ); // 0
