Run results for: JS: append vs prepend vs insertBefore vs appendChild vs insertAdjacentElement in a populated table

The similar tests I found here "test" adding one single node to another singe node. Those tests are quite useless for real world situations. The use case here is that the rows array is sorted (not included) and then the table is restructured accordingly.

HTML Preparation code:

<table><tbody id="body"></tbody></table>

Script Preparation code:

var rows = [];
for (var i = 0; i < 10000; ++i) {
    var row = document.createElement("tr");
    var cell = document.createElement("td");
    cell.appendChild(document.createTextNode(i));
    row.appendChild(cell);
    body.appendChild(row);
    rows.push(row);
}
var nodes = body.childNodes;

Tests:

append
for (var i = 0; i < 10000; ++i) { body.append(rows[i]); }
prepend
for (var i = 0; i < 10000; ++i) { body.prepend(rows[i]); }
insertBefore
for (var i = 0; i < 10000; ++i) { body.insertBefore(rows[9999 - i], nodes[i]); }
appendChild
for (var i = 0; i < 10000; ++i) { body.appendChild(rows[i]); }
insertAdjacentElement
for (var i = 0; i < 10000; ++i) { body.insertAdjacentElement("beforeend",rows[i]); }
