Using Javascript i need to be able to:

1: Push a certain amount of the same function (with a different parameter in each) into an array.

2: Then run each function one by one (for this example just an alert of the parameter/number)

3: After each function i need to be able to SPLICE that function out of the array

4: Check the Array Length after everytime - Once the array is empty again - alert the user it is complete

Now i seem to be able to do task 1,2 and 4 but i am sturggling with how to splice out the function from the array after it has run - can anyone help? As i cannot remove the function i am never getting the 'done' alert once all functions have been called

My javascript code so far is:

Code:
// Create empty array
var array = [];

// Push functions into array - dynamic amount and could be any amount of functions
array.push(func(1));
array.push(func(2));
array.push(func(3));

// Call array manager function after pushing array
arrayManager();

// Array manager function to splice and detect when finished
function arrayManager() {
    if (array.length < 1) {
        alert("done");
    }
    else {
    //////////////////////////////////
    // << THIS IS WHERE I DON'T KNOW HOW TO SPLICE THE ITEM FROM THE ARRAY
    //////////////////////////////////
    }
}

// Function for array objects - alert passed parameter
function func(num){
    alert(num);
}
