How to Use the find() Method in JavaScript array: This represents the target array along with all its items.index: This is the index position of the currentItem inside the array.currentItem: This is the element in the array which is currently being iterated over.The callback function can take in the following parameters: So the find() method returns the first element inside an array which satisfies the callback function. When it finds a match (in other words, the callback function returns true), the method returns that particular array item and immediately breaks the loop. The find() method is an Array.prototype (aka built-in) method which takes in a callback function and calls that function for every item it iterates over inside of the array it is bound to. Well, we can use the find() method to do just that.

And you won't care how many other items (if any) exist within the same array. When you're working with an array collection, sometimes you'll only need to find out if an item exists in the array so you can retrieve it.
