Introduction

In this lab, we will explore the concept of calculating the midpoint between two pairs of (x,y) points using JavaScript. We will learn how to destructure an array to obtain the x and y coordinates of the endpoints and calculate the midpoint for each dimension by dividing the sum of the two endpoints by 2. This lab is designed to enhance our understanding of basic math operations in JavaScript and apply them to solve real-world problems.

Instructions for calculating the midpoint between two pairs of (x,y) points:

To calculate the midpoint between two pairs of (x,y) points, follow these steps:

  1. Destructure the array to get x1, y1, x2 and y2.
  2. Calculate the midpoint for each dimension by dividing the sum of the two endpoints by 2.

Here's an example code snippet that implements the midpoint calculation function:

const midpoint = ([x1, y1], [x2, y2]) => [(x1 + x2) / 2, (y1 + y2) / 2];

You can call the midpoint function with the following parameters to get the midpoint coordinates:

midpoint([2, 2], [4, 4]); // [3, 3]
midpoint([4, 4], [6, 6]); // [5, 5]
midpoint([1, 3], [2, 4]); // [1.5, 3.5]

Getting started with coding:

To start practicing coding, follow these steps:

  1. Open the Terminal/SSH.
  2. Type node to start the Node.js environment.
