Is it really necessary to use array, to display an innerHTML of a complete node list after child remove?

Question

This code works well but when I start to remove nodes the complete list disappear and I'm left with one node in the innerHTML, instead of removing one by one gradually which is what I want. To leave a few to none behind perhaps gradually instead of straight one for all displayed in the innerHTML, of the div that displays the removal sort of say... I can perfectly do this to work using arrays but I'm curious if there's an way out without using any(arrays)?

HTML code

<button onClick="remov()">remove</button>
<button onClick="addDiv()">Add Div</button>
<div>
<div></div>
<div></div><div></div>
<div></div>
</div>
<div id="tt"></div>

Javascript Code

var stage = document.getElementsByTagName("div")[0];
var tt = document.getElementById("tt");

function remov() {
    if (stage.hasChildNodes()) {
        stage.removeChild(stage.firstChild);
        for (var i = 0; i < stage.childNodes.length; i++) {
            tt.innerHTML = stage.childNodes[i].nodeName;
        }

        if (!stage.hasChildNodes()) {
            tt.innerHTML = "no nodes";
        }
    }
}

for (var i = 0; i < stage.childNodes.length; i++) {
    tt.innerHTML += stage.childNodes[i].nodeName;
}

function addDiv() {
    var a = document.createElement("div");
    stage.appendChild(a);
    if (!stage.hasChildNodes()) {
        tt.innerHTML += stage.firstChild.nodeName;
    } else {
        tt.innerHTML += stage.lastChild.nodeName
    }
}

If you want to display all divs during their removal need to change = to += as below

function remov() {
    tt.innerHTML=''; //EDIT forgot to add in this line
    if (stage.hasChildNodes()) {
        stage.removeChild(stage.firstChild);
        for (var i = 0; i < stage.childNodes.length; i++) {
            tt.innerHTML += stage.childNodes[i].nodeName;  //<------- + needed to display all divs
        }

        if (!stage.hasChildNodes()) {
            tt.innerHTML = "no nodes";
        }
    }
}
