Dequeue function
The dequeue object queue function is as follows:
dequeue ()
Removes and returns the item to the beginning of the array. This is equivalent to the array function and Array-remove-function
but adds in readability when using the array as a first-in first-out (FIFO) queue.
Parameters:
This function does not take any parameters
Returns:
The first item in the array.
Example:
q.enqueue("one")
q.enqueue("two")
q.enqueue("three")
// array now contains three items.
one = q.dequeue()
two = q.dequeue()
three = q.dequeue()
// queue is now empty. one is "one", two is "two" and three is "three"
q.enqueue("two")
q.enqueue("three")
// array now contains three items.
one = q.dequeue()
two = q.dequeue()
three = q.dequeue()
// queue is now empty. one is "one", two is "two" and three is "three"
