find method

The find method helps to find the first element in an array according to the callback passed in the parameter. If there is no element, then undefined is returned.

Syntax

array.find(function);

Example

Let's find the array element that matches the conditions specified in a function:

let arr = [1, 2, 3, 4];

let res = arr.find(function(currentValue) {
	return currentValue > 0;
});

console.log(res);

The code execution result:

1

Example

Let's find an array element whose length is 2:

let arr = ['abc', 'defg', 'kl', 'mn'];

let res = arr.find(function(elem) {
	return elem.length == 2;
});

console.log(res);

As a result of executing the code, we will see that the method found the first element that matches the conditions of the function:

'kl'
