Mastering the Sum of Numbers Until N

Introduction

In this lab, we will be exploring the concept of summing all the numbers between 1 and a given number n. We will be using the formula (n * (n + 1)) / 2 to calculate the sum of numbers. Through this lab, you will gain a better understanding of how to solve mathematical problems using programming.

Function to Calculate Sum of Numbers Until N

To calculate the sum of numbers between 1 and n, you can use the formula (n * (n + 1)) / 2. Here's an example code in JavaScript:

const sumN = (n) => (n * (n + 1)) / 2;

To use this function, pass the value of n as an argument. For instance, sumN(100) will return 5050. To start practicing coding, open the Terminal/SSH and type node.
