Web3 Dec 2024 · In this tutorial, you’ll learn how to write a JavaScript program to find sum of N numbers. Sum of N numbers means sum of numbes from 1 to n (n can be 100, 200 etc.) Traditional Approach To Find Sum Of N Numbers. Let’s start by writing a simple JavaScript function which will loop through numbers from 1to N and calculate the sum. WebThe mathematical formula behind the Sum of Series 1 + 2+ 3+ … + N = N * (N + 1) / 2. In this program, we are creating a separate method to calculate the sum of natural numbers. Within the function, we used the If Else statement to check whether the Number is equal to Zero or not. If it is True, the Sum of N Natural numbers = 0.
