adding new object to an object array javascript

Question

I solved this. you are right I was running a function which was the problem. If anyone wants to look at the solution I have attached it below. This was never meant to look nice just function. Thank you for at least looking at it. And to answer question more clearly. This was a debugging assignment as I am working towards a complete understanding through school. As I said I wasn't looking for anyone to solve for me just to guide me so I can solve myself. Most people I have dealt with in the developer community has been super helpful so I simply wanted to reach out for help in my new endeavors. Thank you all for that help. Again I have fully solved all 10 errors which is what the // error# was about and believe will receive 100%. I know debugging probably seems beginner and mundane but we were all beginners once. Again the link to the solved project is below with a copy of the solved and unsolved project if anyone wants to play. This way I offer a benefit to the question having been asked.

object array:

var flavors = [
{
    "flavor": "Vanilla",
    "favorite": "Yes!",
    "notes": "Great for sundaes."
},
{
    "flavor": "Chocolate",
    "favorite": "Yes!",//first error
    "notes": "All parts chocolate. What's not to love?"
},
{
    "flavor": "Neapolitan",
    "favorite": "No",
    "notes": "I dislike the strawberry chunks."
}
];

code to push the form data to the array:

var saveFlavor = function(){

var fav = getFavorite();   
//error 5 not fixed
var newFlavor = function() {
    flavors.flavor = document.getElementById('flavor').value,
    flavors.favorite = fav, //error 6 not fixed 
    flavors.notes = document.getElementById('notes').value //error 7
    };
    flavors.push(newFlavor);
    console.log(newFlavor)

    location.href="#home";
    document.getElementById('list').innerHTML = "";

};
var save = document.getElementById("submitFlavor"); //error 8
save.addEventListener("click", saveFlavor);

Data called on with:

var showFlavors = function(){
for(var i=0, len=flavors.length; i<len; i++){ //error 2
    var newLi = document.createElement('li');   
    document.getElementById('list').appendChild(newLi);
      var heading =document.createElement('h3');
          heading.innerHTML = flavors[i].flavor;
          newLi.appendChild(heading);
  var pNotes = document.createElement('p');
          pNotes.innerHTML= flavors[i].notes;
          newLi.appendChild(pNotes);
  var pFav = document.createElement('p');
        if(flavors[i].favorite == "Yes!") {
            flav = "Yes";
            } else if (flavors[i].favorite == "No") {
            flav = "No";
    };
    console.log(flav)
    pFav.innerHTML= flav; //error 3 
    newLi.appendChild(pFav);
    console.log(newLi); 
};


};

It does push to the Array but returns as Undefined I also dropboxed this code here if you need to see more. https://www.dropbox.com/sh/ee0usbthykoqllg/cZi_K6zst2

I fixed everything else in this debugging process however I am having trouble solving why I am returning undefined. I am not looking at someone giving me the answer, I am looking for guidance as to what I am doing wrong. It did not work at all when I started and I have fixed the rest just need help with this. Thanks.

Could you throw a minimal/SSCCE reproduction of your code into a live demo, where we can play with it, without having to reproduce a page/demo ourselves? And, incidentally, what's with the // error 5 and // error 8 comments? — David Thomas

There's really too many issues with this code for it to be helpful for others in the future, voting to close as "too localised". My advice would be to read a few tutorials on JavaScript. — James

newFlavor isn't an object, it's a function. This is how you create an object:

var newFlavor = {
    flavor: document.getElementById('flavor').value,
    favorite: fav, //error 6 not fixed 
    notes: document.getElementById('notes').value //error 7
};

A function is an object in javascript, isn't it? ;)

Barmar Over a year ago

@meze typeof function() { return 1} returns "function"

Ian Over a year ago

@Barmar If you want to get technical like that, (function () {}) instanceof Object returns true. meze had a ;) in their comment, meaning they weren't saying a function is literally an object - it's obviously something separate

Johnny Over a year ago

A function is an object created from the Function constructor which is an instance of Object.

James Over a year ago

@Ian yeah it was more my understanding on the function itself actually being an object (not really a big JS guy). Deleted the comment incase it causes confusion. However, quick read of this and it all makes sense....functions are objects :)
