+### Distance between two points
+
+Use `Math.pow()` and `Math.sqrt()` to calculate the Euclidean distance between two points.
+
+```js
+var distance = x0, y0, x1, y1 =>
+  Math.sqrt(Math.pow(x1-x0, 2) + Math.pow(y1 - y0, 2))
+```
+
 ### Even or odd number
 
 Use `Math.abs()` to extend logic to negative numbers, check using the modulo (`%`) operator.
