JavaScript: Detecting

arrays.js

Implement and export as default a function that takes an array (whose elements are objects) and key-value pairs (also as an object), and returns the first element of the original array whose values match all passed pairs. If there is no match, the function should return null.

Examples

findWhere(
  [

    { title: 'Cymbeline', author: 'Shakespeare', year: 1611 },

    { title: 'Happy Foo', author: 'FooBar', year: 4444 },
