Sum of Square of First N Natural Numbers using for Loop
The for loop is used to calculate the sum of the squares of first N natural numbers. First, initialize a variable sum with 0 then iterating over the numbers from 1 to N and adding the square of each number to the sum variable.
Syntax:
for (initialization; condition; update) {
// Code
}
Example: This example uses the for loop to get a sum of squares of first n natural numbers in JavaScript.
let n = 8;
let sum = 0;
for (let i = 1; i <= n; i++) {
sum += i * i;
}
console.log(sum);
Output
204
