find() - FUNCTION

find() Function is used to return the first element of the array that satisfies a given condition.

Let us say, we have a Array that contains five numbers, 5, 8, 2, 81 and 9.

And we want to find the element 8 from the Array.

And find() gives us an elegant way to do it.

Let us see in the below example.

Example :

<html>
<body>  
<script>

	function numberCheck(i) {
  		return i == 8
	}

	var x = [5, 8, 2, 81, 9]
	var y = x.find(numberCheck)
	
    document.write(y)
	    
</script>      
</body>
</html>

Output :

So, we have an Array that has 5 numbers.

And we want to find the element 8 from the Array.

We have defined a function called numberCheck(), that checks if a number is equal to 8.

function numberCheck(i) {
	return i == 8
}

And we have called the above function from find() function.

var y = x.find(numberCheck)

And find() function iterates 5 times(i.e. The length of the array), calling numberCheck() function.

var y = x.find(numberCheck)

And it the moment it finds 8 the execution is stopped.

Printing 8 as output
