### VectorDistance
|
|
|
|
Returns the distance between two points.
|
|
|
|
Splits the arguments array into two points. Use `Array.prototype.reduce()`,`Math.pow()` and `Math.sqrt()` to calculate the Euclidean distance between two vectors.
|
|
|
|
```js
|
|
const vectorDistance = (...coords) => {
|
|
let length = Math.trunc(coords.length/2);
|
|
let sum = coords.slice(0,length).reduce((accumulator,currentValue,currentIndex) => accumulator + (Math.pow(currentValue-coords[length+currentIndex],2)),0);
|
|
return Math.sqrt(sum);
|
|
}
|
|
```
|
|
|
|
```js
|
|
vectorDistance(10,0,5,20,0,10) //11.180339887498949
|
|
```
