# REVERSE

*[View on tines.com](https://www.tines.com/docs/formulas/functions/reverse/)*

Reverses the order of the elements in an array. Please note, this operation will recursively flatten arrays and directly nested arrays, then reverse the final array.

**Categories:** Arrays

## Syntax

```
REVERSE(array)
```

## Examples

### Example 1

Input:

```json
{
  "my_action": {
    "message": [
      "north",
      "south",
      "east",
      "west"
    ]
  }
}
```

Formula:

```
REVERSE(my_action.message)
```

Output:

```json
[
  "west",
  "east",
  "south",
  "north"
]
```

### Example 2: REVERSE can't directly reverse an individual piece of text, but you can combine it with SPLIT and JOIN to make it work:

Input:

```json
{
  "my_action": {
    "message": "edit maps"
  }
}
```

Formula:

```
JOIN(REVERSE(SPLIT(my_action.message, "")), "")
```

Output:

```json
"spam tide"
```

### Example 3: REVERSE also flattens arrays

Input:

```json
{
  "my_action": {
    "message": [
      [
        1,
        2,
        3
      ],
      [
        4,
        5,
        6
      ],
      [
        7,
        8,
        9
      ]
    ]
  }
}
```

Formula:

```
REVERSE(my_action.message)
```

Output:

```json
[
  9,
  8,
  7,
  6,
  5,
  4,
  3,
  2,
  1
]
```
