Dequeue function

dequeue object queue.

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"
