Program in Javascript to find the sum of N Natural Numbers - using while Loop

The below function will help us to find the sum of N Natural numbers using while loop

function SumofNNaturalNumbers() {

                var N=10;
                var sum = 0;
                var i=1;
                while(i<=N) {
                        sum+=i;
                        i++;
                }   
                alert("Sum Of N Natural Numbers : " + sum);
            }

We are looping through the numbers till it reaches the maximum end and summing the individual numbers. Finally, printing the same using the alert.
