npm install randoma
```

## Usage

```js
import Randoma from 'randoma';

const random = new Randoma({seed: 10});

random.integer();
//=> 2027521326

random.integer();
//=> 677268843


(new Randoma({seed: '🦄'}).integer());
//=> 1659974344

(new Randoma({seed: '🦄'}).integer());
//=> 1659974344
```

## API

### `const random = new Randoma(options)`

#### options

Type: `object`

##### seed

*Required*\
Type: `string | number`

[Initialization seed.](https://en.m.wikipedia.org/wiki/Random_seed)

Multiple instances of `Randoma` with the same seed will generate the same random numbers.

#### random.integer()
#### random.integerInRange(minimum, maximum)
#### random.float()
#### random.floatInRange(minimum, maximum)
#### random.boolean()
#### random.arrayItem(array)
#### random.date()
#### random.dateInRange(startDate, endDate)

#### random.color(saturation?)

Returns a random [aesthetically pleasing color](https://martin.ankerl.com/2009/12/09/how-to-create-random-colors-programmatically/) as a [`color`](https://github.com/Qix-/color) object.

random.color(0.5).hex().toString()
//=> '#AAF2B0'
```
