JavaScript Algorithm: Find the Perimeter of a Rectangle

Today, we are going to write a function called findPerimeter that will accept two integers, length and width, as arguments.

You are given the length and the width of a rectangle. The goal of the function is to output the perimeter of that rectangle. I don’t know when in school you start learning simple geometry but you use this is how you calculate the perimeter of a rectangle:

perimeter = (length + width) * 2
perimeter = length + length + width + width
perimeter = (length * 2) + (width * 2)

All of the examples above are the multiple ways you can get the perimeter of a rectangle. They’re all done differently but they all lead to the same answer.

Now that I helped you re-learn geometry, here are a couple of examples:

findPerimeter(6, 7) ➞ 26
findPerimeter(20, 10) ➞ 60

If you plug in those input values into the perimeter formulas above, your function will output the numbers following the arrow.

Here is a step by step process for the first example.

Length = 6
Width = 7

Perimeter = (6 + 7) * 2
Perimeter = (13) * 2
Perimeter = 26

Now that you understand this, let’s turn this into code.

Javascript array find: How to Find Element in Javascript

Javascript array find() is an inbuilt js function that returns the value of the first item in the Array that satisfies a provided testing function. Otherwise,  undefined will be returned. The array find() method returns the value of the first element in an array that passes a test of provided function.

If an Array find() method finds an item where the function returns a true value. Javascript find() returns the value of that array item immediately and does not check the remaining values of that Array.

Javascript array find

Javascript Array.find() is the inbuilt function that is used to get a value of the first item in the Array that meets the provided condition. If you need an index of the found item in the Array, use the  findIndex(). If you need to find an index of the value, use Array  .prototype.indexOf(). If you need to find if the value exists in an array, use Array  .prototype.includes().

It checks all the items of the Array, and whichever the first item meets, the condition is going to print. If more than one item meets the condition, then the first item satisfying the requirement is returned. Suppose that you want to find the first odd number in the Array. The argument function checks whether an argument passed to it is an odd number or not.

Javascript find() function calls an argument function for every item of the Array.  The first odd number for which argument function returns true is reported by the find() function as the answer.
