I dont understand fully what this is doing. Please explain

$(document).ready(function(){ $(document).on('click','item', function() { $(this).remove(); $('#button').click(function(){ var toAdd= $('input[name=checkListItem]').val(); $('.list').append('<div class='item>' + toAdd +'</div>'); }); })'

I went through and commented each line to the best of my abilities so you could see exactly what's going on. There was a single quote mark in the append() function which was an issue and you didn't have the final closing }); or whatever that's called. I didn't test the code to see if it actually does what it's supposed to, but at least you now know what each line means.

Also, that append() function is doing nothing useful in this code. Inside the parenthesis is where you would put what you want to append to elements with the "list" class.

$(document).ready(function(){  /* Waits until page is fully loaded to start what this function contains */

    $(document).on('click','item', function() { /* When document is clicked, do function on 'item' */

        $(this).remove();  /* Remove 'item' from the page */

        $('#button').click(function(){ /* When the element with the ID of "button" is clicked */

            var toAdd= $('input[name=checkListItem]').val(); /* Create variable "toAdd" with the value of the input field with the name "checkListItem" */

            $('.list').append(); /* Append nothing to the element with the class "list" */

        }); /* Closes button click function */

    }); /* Closes item click function */

}); /* Closes ready function (wasn't originally in code) */

I understand. I get what was confusing me. Inside of append('<p>' + toAdd +'</p>'). I understand that now that what ever was in the class 'list' had to put in the value of input which was the variable toAdd, at the end of the element .list.
