This "most effective tool" looks like a fancy way of concatenating HTML strings in JS. :)

Hardly something that can be described as quality software engineering.

That's just silly. Ultimately every tool outputs a 'string' that gets sent to the browser.

What matters is how this happens, and there's a huge difference between React's approach and '<div class="whoops"><?php echo $some_unescaped_dangerous_thing ?></div>'
