Answer 1

2018 Update:

Use ChildNode.replaceWith() method. As exemplified in MDN docs:

var parent = document.createElement("div");
var child = document.createElement("p");
parent.appendChild(child);
var span = document.createElement("span");

child.replaceWith(span);

console.log(parent.outerHTML);
// "
"
