0. **Array `map()` Method:**

Creates a new array with each element in the array `[1, 2, 3, 4]` multiplied by 2, resulting in `[2, 4, 6, 8]`.

1. **Array `pop()` Method:**

```javascript
[1, 2, 3, 4].pop();
```
Removes the last element from the array `[1, 2, 3, 4]` and returns it, resulting in `4`. The array becomes `[1, 2, 3]`.

2. **Array `push()` Method:**

```javascript
[1, 2, 3, 4].push(5);
```
Adds the element `5` to the end of the array `[1, 2, 3, 4]` and returns the new length, resulting in `5`. The array becomes `[1, 2, 3, 4, 5]`.
