### Array zip

Use `Math.max.apply()` to get the longest array in the arguments.
Creates an array with that length as return value and use `Array.from()` with a map-function to create an array of grouped elements.
If lengths of the argument-arrays vary, `undefined` is used where no value could be found.

```js
const zip = (...arrays) => {
  const maxLength = Math.max(...arrays.map(x => x.length));
  return Array.from({length: maxLength}).map((_, i) => {
   return Array.from({length: arrays.length}, (_, k) => arrays[k][i]);
  })
}
//zip(['a', 'b'], [1, 2], [true, false]); -> [['a', 1, true], ['b', 2, false]]
//zip(['a'], [1, 2], [true, false]); -> [['a', 1, true], [undefined, 2, false]]
```
