What is the output of the following JavaScript code? | Question 15

64. What will be the output of the following JavaScript code?

<script>
	var values = [10, 20, 30, 40];
	
	var result = values.reduceRight(function(x,y){
		return (x + y);
	});
	
	document.write("Result: " + result);
</script>

1. Result: 40
2. Result: 70
3. Result: 90
4. Result: 100

Answer: D) Result: 100

Explanation:

In the above JavaScript code, we used the reduceRight() method which is used to reduce the given array elements into a single value by executing a reducer function. The reducer() function is applied against the accumulator and reduces all the elements from right to left. Thus, the output would be "Result: 100".
