window.onload = function(){ // window.onload so our javascript code loads after our html doc is loaded var colors=[ "purple", "orange", " yellow", "green", "blue", "red" ]; var squares =document.querySelectorAll(".square"); for(var i=0; i<squares.length; i++){ //alert(); // this was annoying don't do this ever!!! // squares[i].background=colors[i]; // you must access the backgroundColor from the style property of the element (squares[i]).style.backgroundColor= colors[i] } } // onload end #working example below https://code.sololearn.com/WT7RqfM47daM/?ref=app

idris Instead of alert() try doing a console.log('txt') it's less intrusive. It's wasn't necessary to add parens in that context, did it as it was neat & more clear to me.

Lord Krishna the reason i put the alert in there was to check if the for loop was actually working i forgot to remove it. Also why was (squares[i]) but in a bracket i dont get that part please could you explain
