how to add user data javascript

I am having trouble being able to add user input data. I can get it working when I add in the data myself all the users show up in the console in the array. For people 1-3 I would like them to enter their name and favorite color but I can’t seem to be able to store it or at least have it come up in the console. I did remove person 2 and 3 from the array so I can test it easier and quicker. if you were to take the

    user: document.getElementById('name').value,
    color: document.getElementById('color').value,

and all the comments it would work and show up in console how i want it to but cant seem to do user data. Sorry if this is confusing i am a new to javascript.
