# Vector distance

JavaScript, Math, Algorithm · Dec 28, 2020

Calculates the distance between two vectors.

- Use
`Array.prototype.reduce()`

,`Math.pow()`

and`Math.sqrt()`

to calculate the Euclidean distance between two vectors.

```
const vectorDistance = (x, y) =>
Math.sqrt(x.reduce((acc, val, i) => acc + Math.pow(val - y[i], 2), 0));
```

`vectorDistance([10, 0, 5], [20, 0, 10]); // 11.180339887498949`
