The Find Method In JavaScript

The Find Method In JavaScript: Hello everyone, welcome to the website. In this article we will going to discuss about the The Find Method In JavaScript.

The Find Method In JavaScript

The find method in JavaScript is a built-in function on the Array object that returns the value of the first element in the array that satisfies the provided testing function. If no element passes the test, undefined is returned.


array.find(function(currentValue, index, array) {
  // code to determine if element is the desired value
  return element;


  • function is the callback function that will be executed for each element in the array.
  • currentValue is the current value being processed in the array.
  • index is the index of the current value being processed in the array.
  • array is the original array that find was called upon.

find Method To Find The First Positive Number In An Array

Here’s an example of using the find method to find the first positive number in an array:

let numbers = [-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5];
let firstPositive = numbers.find(function(currentValue) {
  return currentValue > 0;

console.log(firstPositive);  // Output: 1



Here’s another example of using the find method to find an object in an array based on a specific property:

let users = [
  { id: 1, name: 'John' },
  { id: 2, name: 'Jane' },
  { id: 3, name: 'Jim' }

let user = users.find(function(currentValue) {
  return === 2;



{ id: 2, name: 'Jane' }

And here’s an example of using the find method with an arrow function for conciseness:

let numbers = [1, 2, 3, 4, 5];
let firstEven = numbers.find(currentValue => currentValue % 2 === 0);
