findPerimeterHexagon()

Step 1: Understand the problem

The task is to write a programming function in JavaScript, findPerimeterHexagon, that calculates the perimeter of a hexagon. A hexagon is a six-sided polygon and the length of the perimeter of a hexagon is the total length of its sides. So if we know the length of one side, we can simply multiply it by 6 to get the perimeter.

Here's the start of our function:

function findPerimeterHexagon(sideLength) {
    //todo
}

Step 2: Define the parameter

Our function will receive one parameter, sideLength, which represents the length of one side of the hexagon. This is the foundation of the function, and the parameter we will use to calculate the perimeter.

function findPerimeterHexagon(sideLength) {
    //the side length of the hexagon is received as a parameter
}

Step 3: Calculation

Inside the function, we'll calculate the perimeter by multiplying the sideLength by 6, since a hexagon has six sides. We store this result in a variable called perimeter.

function findPerimeterHexagon(sideLength) {
    //the perimeter is the side length multiplied by 6
    let perimeter = sideLength * 6;
}

Step 4: Returning the result

In JavaScript, to return a value from a function, we use the return keyword. So, we'll return the perimeter from our function.

function findPerimeterHexagon(sideLength) {
    let perimeter = sideLength * 6;
    //return the calculated perimeter
    return perimeter;
}

Conclusion:

That's it! Our function is complete. Here's the final implementation.

function findPerimeterHexagon(sideLength) {
    let perimeter = sideLength * 6;
    return perimeter;
}

We can now use this function to find the perimeter of any hexagon given the length of one side. For example, findPerimeterHexagon(5) would give us a perimeter of 30.
