It appears that the slice function is not functioning correctly within an array of functions

My code includes a function called UIAlerts:

function UIAlerts() {}

I then use the prototype methodology to assign a variable to this function:

UIAlerts.prototype.questions = []

Next, I add a function to this array:

UIAlerts.prototype.questions.push(function(){
     //perform an action
});

When a click event occurs, the following code is executed:

if (UIAlerts.prototype.questions && UIAlertController.prototype.questions.length > 0) {
        UIAlerts.prototype.questions.slice(0, 1);
        UIAlerts.prototype.questions[0] && UIAlertController.prototype.questions[0]();
}

if (UIAlerts.prototype.questions.length == 0)
    UIAlerts.prototype.questions = undefined;

The issue I am facing is that the slice method does not remove the first item in the function array. Any suggestions?

Answer №1

The slice method does not alter the original array; instead, it creates a new copy of the specified section.

If you want to actually modify the original array, you should use Array.prototype.splice.
