Using the `toString()` method on an array will return a string representation of the array:

```js
const list = [1, 2, 3, 4]
list.toString()
```

The `join()` method of an array returns a concatenation of the array elements:

```js
const list = [1, 2, 3, 4]
list.join()
```

We can pass a parameter to this method to add a custom separator:

```js
a.join(', ')
```
