The Array.find() and Array.findIndex() methods allow you to find elements in an array based on a condition.

find_array.js

// Longhand
const numbers = [1, 2, 3, 4, 5];
let foundNumber;
for (let i = 0; i < numbers.length; i++) {
  if (numbers[i] > 3) {
    foundNumber = numbers[i];
    break;
  }
}

// Shorthand
const numbers = [1, 2, 3, 4, 5];
const foundNumber = numbers.find((number) => number > 3);
const foundIndex = numbers.findIndex((number) => number > 3);
