+### midpoint
+
+Calculates the midpoint between two pairs of x and y points.
+
+Takes in two pairs of (x,y) points, calculates the midpoint between the x's, the midpoint between the y's, and returns the coordinates in an array.
+
+```js
+const midpoint = (x1, y1, x2, y2) => {
+  let points = new Array(2);
+  let first_point = (x1 + x2) / 2;
+  let second_point = (y1 + y2) / 2;
+
+  points[0] = first_point;
+  points[1] = second_point;
+  return points;
+};
+```
+
+```js
+midpoint(2, 2, 4, 4); // [3, 3]
+midpoint(4, 4, 6, 6); // [5, 5]
+midpoint(1, 3, 2, 4); // [1.5, 3.5]
+```
