### join
Joins all elements of an array into a string and returns this string. Uses a separator and an end separator.
Use `Array.reduce()` to combine elements into a string.
Omit the second argument, `separator`, to use a default separator of `','`.
Omit the third argument, `end`, to use the same value as `separator` by default.
```js
const join = (arr, separator = ',', end = separator) =>
arr.reduce(
(acc, val, i) =>
i == arr.length - 2
? acc + val + end
: i == arr.length - 1 ? acc + val : acc + val + separator,
''
);
```
<details>
<summary>Examples</summary>
```js
join(); // ''
join(['pen', 'pineapple', 'apple', 'pen'], ',', '&'); //"pen,pineapple,apple&pen"
join(['pen', 'pineapple', 'apple', 'pen'], ','); //"pen,pineapple,apple,pen"
join(['pen', 'pineapple', 'apple', 'pen']); //"pen,pineapple,apple,pen"

### mask
Replaces all but the last `num` of characters with the specified mask character.
Use `String.slice()` to grab the portion of the characters that need to be masked and use `String.replace()` with a regex to replace every character with the mask character.
Concatenate the masked characters with the remaining unmasked portion of the string.
Omit the second argument, `num`, to keep a default of `4` characters unmasked.
Omit the third argument, `mask`, to use a default character of `'*'` for the mask.
```js
const mask = (cc, num = 4, mask = '*') =>
('' + cc).slice(0, -num).replace(/./g, mask) + ('' + cc).slice(-num);
