How to use find() method In Javascript
The Javascript arr.find() method is used to get the value of the first element in the array that satisfies the provided condition. It checks all the elements of an array and whichever the first element satisfies the condition is going to print. This function will not work having the empty array elements and also does not change the original array.
Syntax:
array.find(function(currentValue, index, arr), thisValue);
Example: In this example, we will use the Javascript Array find() method to search for an element in an array. This method searches for the first element that is greater than 50 and returns it.
const arr = [25, 33, 22, 45, 67, 1, 32, 223];
const greaterElement = arr.find(ele => ele > 50);
console.log(greaterElement);
Output
67
