Question

I’m new to Javascript and been learning. I’m trying to set a button to activate random functions. button is fine and if I assign getGroupOne() to a button or getGroupTwo() to a button it works fine.

The only problem is somewhere in the following code.

Well when I click my button only getGroupTwo() works with the following code,

function getGroup() {
    var Group = new Array (getGroupOne(), getGroupTwo());
    var whichOne = Math.floor(Math.random()*Group.length); 
        return Group[whichOne];};

But when I flip them … only getGroupOne() works with the following code,

function getGroup() {
    var Group = new Array (getGroupTwo(), getGroupOne());
    var whichOne = Math.floor(Math.random()*Group.length); 
        return Group[whichOne];};

Could someone let me know what is the problem, I looked at a couple answers but not completly sure how to fix this.

Thank you,

If you want to return function references, you should write it like this:

function getGroup() 
{
    var Group = [getGroupOne, getGroupTwo],
    whichOne = Math.floor(Math.random() * Group.length);

    return Group[whichOne];
}

getGroup()();
