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());
|
//=> '🌈'
|
```
