Let us say we have a callback function as shown in the listing below.

array: the array on which the find method is being called.

index: the index of the current element being processed.element: the current element being processed in the array.

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.

If the callback returns a truthy value, the. The callback function parameter of the find method takes three parameters: 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. The find() executes the callback function for each element in the array until the callback returns a truthy value. An object which will be the value of this in the callback function is an optional parameter, and if it’s not passed, the value will be set to undefined in the callback function.The callback function will be called for each element of the array until the given condition for a particular element is not true.It takes two parameters, one required callback function and an optional object, which will be set as a value of this inside the callback function. This returns a value on a given criterion, otherwise, it returns ‘undefined’. To search a particular object, we will use the Array prototype find method.
