The size of the queue.

/**
Tiny queue data structure.
The instance is an [`Iterable`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols), which means you can iterate over the queue front to back with a “for…of” loop, or use spreading to convert the queue to an array. Don't do this unless you really need to though, since it's slow.
@example
```
import Queue = require('yocto-queue');
const queue = new Queue();
queue.enqueue('🦄');
queue.enqueue('🌈');
console.log(queue.size);
//=> 2
console.log(...queue);
//=> '🦄 🌈'
console.log(queue.dequeue());
//=> '🦄'
console.log(queue.dequeue());
//=> '🌈'
```

/**
Add a value to the queue.
*/

/**
Remove the next value in the queue.
@returns The removed value or `undefined` if the queue is empty.
*/
dequeue(): ValueType | undefined;
/**
Clear the queue.
*/
clear(): void;
