Explanation of .dequeue()

What does .dequeue() do? It removes a function from the specified jQuery animation queue and executes it. In the example below, you can see the method changing the size and color of the element:

Here is the syntax you would use for jQuery .dequeue():

$("selector").dequeue(queue);

Introducing .clearQueue()

To remove all animations from the queue on the selected element, use .clearQueue(). In the example below, you may start the first animation, and prevent the second one from executing by clicking the button:

$("button").click(() => {
    $("div").clearQueue();
});

Here is the syntax you would use for this method:

$("selector").clearQueue(queue);

Note: in all of these cases, the syntax takes a single argument, defining the name of the jQuery animation queue. The default value is the standard effects queue fx.
