Cube - Queue

You can initialize an empty queue or a queue with some elements:

import cube from '@gabrielrufino/cube'

const queue1 = new cube.Queue()
const queue2 = new cube.Queue(1, 2, 3, 4)

Use the property .data to access the elements in the queue:

import cube from '@gabrielrufino/cube'

const queue = new cube.Queue(1, 2, 3, 4)
console.log(queue.data) // [ 1, 2, 3, 4 ]

Use the property .size to get how many elements the queue has:

import cube from '@gabrielrufino/cube'

const queue = new cube.Queue(1, 2, 3, 4)
console.log(queue.size) // 4

Use the method .enqueue() to put a new element at the end of the queue:

import cube from '@gabrielrufino/cube'

const queue = new cube.Queue(1, 2, 3)
queue.enqueue(4);
console.log(queue.data) // [ 1, 2, 3, 4 ]

Use the method .dequeue() to get and remove the first element of the queue:

import cube from '@gabrielrufino/cube'

const queue = new cube.Queue(1, 2, 3, 4)
const element = queue.dequeue();
console.log(queue.data) // [ 2, 3, 4 ]
console.log(element) // 1

Use the method .peek() to get the first element of the queue without removing:

import cube from '@gabrielrufino/cube'

const queue = new cube.Queue(1, 2, 3, 4)
const element = queue.peek()
console.log(queue.data) // [ 1, 2, 3, 4 ]
console.log(element) // 1

Use the method .clear() to remove all the elements in the queue:

import cube from '@gabrielrufino/cube'

const queue = new cube.Queue(1, 2, 3, 4)
queue.clear()
console.log(queue.data) // []
