# Output a single-linked list

Let's say we have a single-linked list (as described in the chapter <info:recursion>):

```js
let list = {
  value: 1,
  next: {
    value: 2,
    next: {
      value: 3,
      next: {
        value: 4,
        next: null
      }
    }
  }
};
```

Write a function `printList(list)` that outputs list items one-by-one.

Make two variants of the solution: using a loop and using recursion.

What's better: with recursion or without it?
