calculateHypotenuse()

Step 1: Understanding the Problem

The first step in solving any problem using code is to understand what problem you are trying to solve. In this case, we want to write a function in JavaScript named calculateHypotenuse that calculates the length of the hypotenuse given the lengths of the other two sides of a right triangle (these are usually referred to as the base and height). From the Pythagorean theorem, we know that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides, or in simpler terms, hypotenuse² = base² + height². To get the length of the hypotenuse, we simply need to find the square root of the sum of the squares of the base and height.

Step 2: Define the Function and Parameters

The second step would be to define our function and its parameters. The function would take two parameters - one for the length of the base and one for the height.

The function will be named calculateHypotenuse, and the parameters would be base and height.

function calculateHypotenuse(base, height) {
    
}

Step 3: Implement the formula

Next, we should use the Pythagorean theorem to calculate the length of the hypotenuse inside our function.

The formula for calculating the length of the hypotenuse in terms of the base and height is:

hypotenuse = √(base² + height²)".

In JavaScript, you can square a number using the ** operator, and you can calculate the square root of a number using the Math.sqrt function.

function calculateHypotenuse(base, height) {
    let hypotenuse = Math.sqrt(base**2 + height**2);
}

Step 4: Return the result

Now that we have calculated the hypotenuse, we need our function to return that value. We do this with the return statement:

function calculateHypotenuse(base, height) {
    let hypotenuse = Math.sqrt(base**2 + height**2);
    return hypotenuse;
}

Conclusion:

Once you follow these steps correctly, you should now have an implemented calculateHypotenuse function. The function takes in two parameters (the lengths of the base and the height of a right triangle) and returns the length of the hypotenuse. Here's the full code:

function calculateHypotenuse(base, height) {
    let hypotenuse = Math.sqrt(base**2 + height**2);
    return hypotenuse;
}

With this function, you can simply call it with two arguments representing the length of the base and the height of the right triangle, and it will return the length of the hypotenuse.
