# `randomInt`

## Description

* Function notation
* Method notation

```
randomInt(upperBound: number): number
```

```
(upperBound: number).randomInt(): number
```

## Arguments

| Name         | Type     | Required | Description                                     |

| `upperBound` | `number` | **true** | The exclusive upper limit for the random number |

## Example

**Use case: Generate a random integer within a range**

Create a pseudorandom integer between `0` and `99` and attach it to each document.

### Example data

```
{

    "event": "login_attempt"

}
```

### Example query

* Function notation
* Method notation

```

```

### Example output

```
{

    "event": "login_attempt",
