# Midpoint

JavaScript, Math · Oct 21, 2020

Calculates the midpoint between two pairs of (x,y) points.

- Destructure the array to get
`x1`

,`y1`

,`x2`

and`y2`

. - Calculate the midpoint for each dimension by dividing the sum of the two endpoints by
`2`

.

const midpoint = ([x1, y1], [x2, y2]) => [(x1 + x2) / 2, (y1 + y2) / 2]; midpoint([2, 2], [4, 4]); // [3, 3] midpoint([4, 4], [6, 6]); // [5, 5] midpoint([1, 3], [2, 4]); // [1.5, 3.5]
