You should use this package instead of an array if you do a lot of `Array#push()` and `Array#shift()` on large arrays, since `Array#shift()` has [linear time complexity](https://medium.com/@ariel.salem1989/an-easy-to-use-guide-to-big-o-time-complexity-5dcf4be8a444#:~:text=O(N)%E2%80%94Linear%20Time) *O(n)* while `Queue#dequeue()` has [constant time complexity](https://medium.com/@ariel.salem1989/an-easy-to-use-guide-to-big-o-time-complexity-5dcf4be8a444#:~:text=O(1)%20%E2%80%94%20Constant%20Time) *O(1)*. That makes a huge difference for large arrays.

> A [queue](https://en.wikipedia.org/wiki/Queue_(abstract_data_type)) is an ordered list of elements where an element is inserted at the end of the queue and is removed from the front of the queue. A queue works based on the first-in, first-out ([FIFO](https://en.wikipedia.org/wiki/FIFO_(computing_and_electronics))) principle.

queue.enqueue('🌈');
|
|
|

console.log(queue.size);
|
|
//=> 2
|
|
|

## API
|
|
|
|
### `queue = new Queue()`
|
|
|
|
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.
|
|
|
|
#### `.enqueue(value)`
|
|
|
|
Add a value to the queue.
|
|
|
|
#### `.dequeue()`
|
|
|
|
Remove the next value in the queue.
|
|
|
|
Returns the removed value or `undefined` if the queue is empty.
|
|
|
|
#### `.clear()`
|
|
|
|
Clear the queue.
|
|
|
|
#### `.size`
|
|
|
|
The size of the queue.
