So I have written some code for my brothers birthday present and it needs to function, however he uses mac or linux while I use windows and I was wondering if the enter key is registered the same.

Here's my code

document.getElementById("input").onkeypress = function(event){
                if (event.keyCode == 13 || event.which == 13){
                    newUserLine();
                    runFunction();
                    window.scrollTo(0,document.body.scrollHeight);
                    document.querySelector('#input').value = '';
                }
            }
