### generateScramble

Generates a random scramble for the given cube size.

**Parameters**

-   `$0` **any**  (optional, default `{}`)
    -   `$0.cubeSize`   (optional, default `3`)
    -   `$0.length`   (optional, default `(cubeSize-2)*20||8`)
    -   `$0.formatted`   (optional, default `true`)

**Examples**

```javascript
import generateScramble from 'scramble-generator';
generateScramble();
// R' U F D' L ...

generateScramble({ cubeSize: 3, formatted: false });
// [ { face: 'U', inverted: false, double: true },
// { face: 'R', inverted: true, double: false },
// { face: 'D', inverted: false, double: true }, ... ]
```

Returns **([string](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String) \| [Array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array)&lt;Move>)** 

### formatScramble

Formats a given scramble as a string.

**Parameters**

-   `scramble` **[Array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array)&lt;Move>** List of Move objects representing a scramble to be formatted.

**Examples**

```javascript
import { formatScramble } from 'scramble-generator';
import { Faces } from 'scramble-utils-common';
format([{
  face: Faces.R,
  inverted: true
}, {
  face: Faces.U,
  double: true
}, {
  face: Faces.L
}])
// "R' U2 L"
```

Returns **[string](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String)** String representation of the given scramble.

## Upgrading

### From v0.1.x

**v0.2.0 has breaking changes**. To upgrade from an earlier version:

```javascript
// Before:
import { formatted, generate, format, parse } from 'scramble-generator';

formatted(); // R U' D ...
const scramble = generate(); // [{ face: 'R', longFace: 'RIGHT', inverted: true, double: false }, ...]
format(scramble) // R' ...
parse("R' U L") // [{ face: 'R', longFace: 'RIGHT', inverted: true, double: false }, ...]

// After
import generateScramble, { formatScramble } from 'scramble-generator';
import parseScramble from 'scramble-parser';

generateScramble(); // R U' D ...
const scramble = generateScramble({ formatted: false }); // [{ face: 'R', inverted: true, double: false }, ...] (NB: `longFace` has been removed)
formatScramble(scramble); // R' ...
parseScramble("R' U L"); // [{ face: 'R', inverted: true, double: false }, ...] (NB: `longFace` has been removed)
```

These breaking changes are necessary to facilitate moving towards v1.0.0, after which the package will adhere strictly to semver. There might be some more breaking changes
