javascript
Parameters: number start, number end
start and end numbers to define the range of numbers to square
Returns: This function returns the total sum of squared numbers
The findSumSquaresRange function in JavaScript is designed to calculate the sum of squares within a provided range of numbers. It totals the square of each number from the start to the end of the range.
Hello there, fellow programmer! In the following sections, we will be diving into a concise and interesting piece of JavaScript coding - how to programme the findSumSquaresRange function. This function is intended to find the sum of the squares of numbers within a specified range. We will be walking through the coding process step by step, making each detail clear along the way. Remember, understanding each part will help you master the concept as a whole. So let's get started, and happy coding!
The first step is to create a function called 'findSumSquaresRange'. This function will take two parameters: 'start' and 'end'. These two parameters represent the range of numbers we want to add their squares.
function findSumSquaresRange(start, end) {
}
Inside this function, let's initialize a variable 'sum' to 0. This variable will hold the final sum of squares of all numbers in the given range.
function findSumSquaresRange(start, end) {
let sum = 0;
}
Next, we need to iterate through all numbers from 'start' to 'end', inclusive. We can do this using a 'for' loop. For each number, we square it and add it to the 'sum'.
function findSumSquaresRange(start, end) {
let sum = 0;
for(let i=start; i<=end; i++) {
sum += i * i;
}
}
Now that we have added up the squares of all numbers in the range, it's time to return the 'sum'. Add a return statement at the end of the function.
function findSumSquaresRange(start, end) {
let sum = 0;
for(let i=start; i<=end; i++) {
sum += i * i;
}
return sum;
}
In conclusion, we have created a function that sums up the squares of all numbers in a given range. This function can be used in various computations where you need to get the sum of squares of numbers in a certain range.
Here is the final code:
function findSumSquaresRange(start, end) {
let sum = 0;
for(let i=start; i<=end; i++) {
sum += i * i;
}
return sum;
}
This function is based on the mathematical principle of squaring numbers and performing addition. To square a number is to multiply it by itself (`n * n`). The sum is then obtained by iterating over a range of numbers and continuously adding the squares of each individual number to a total sum.
