Closed dfilatov closed 8 years ago

dfilatov commented 8 years ago

Currently textContent property is always used in corresponding patch operation to update text. In case of update previous text node, nodeValue property can be used to increase performance.

const firstChild = domNode.firstChild;
if(firstChild) {
    firstChild.nodeValue = newText;
}
else {
    domNode.textContent = newText;
}
