What do you think would be the output? [HTML Collection | NodeList]

Suppose we have the following HTML structure.

<div>Hello World</div>
<div>How are you?</div>

What would be the output if we run the following code snippet?

var divs = document.getElementsByTagName("div");

for ( var i = 0; i<divs.length; i++ ) {
	divs[i].appendChild(document.createElement("div"));
}

console.log(divs.length);
