Calculates the distance between two vectors.
|
|
|
|
- Use `Array.prototype.reduce()`, `Math.pow()` and `Math.sqrt()` to calculate the Euclidean distance between two vectors.
|
|
|
|
```js
|
|
const vectorDistance = (x, y) =>
|
|
Math.sqrt(x.reduce((acc, val, i) => acc + Math.pow(val - y[i], 2), 0));
|
|
```
|
|
|
|
```js
|
|
vectorDistance([10, 0, 5], [20, 0, 10]); // 11.180339887498949
|
|
```
