const array = [1, 2, 3, 4, 5];
const found = find(array, function(element) {
return element > 3;
});
console.log(found); // Output: 4Lodash is a modern JavaScript utility library delivering modularity, performance, and extras. It includes a `find` method that works similarly to array-find but offers a broader range of utility functions for working with arrays, objects, and other data types.

Ponyfill: A polyfill that doesn't overwrite the native method.
Find array elements. Executes a callback for each element, returns the first element for which its callback returns a truthy value.
var find = require('array-find');
var numbers = [1, 2, 3, 4];
find(numbers, function (element, index, array) {
return element === 2;
});
// => 2
var robots = [{name: 'Flexo'}, {name: 'Bender'}, {name: 'Buster'}];
find(robots, function (robot, index, array) {
return robot.name === 'Bender';
});
// => {name: 'Bender'}
find(robots, function (robot, index, array) {
return robot.name === 'Fry';
});
// => undefined
Optionally pass in an object as third argument to use as this when executing callback.
