142. lit-html 1 - tagged templates

Here is a possible implementation of html() and render():

function html(strings, ...values) {
  let result = strings[0];
  for (let i = 0; i < values.length; i++) {
    result += values[i] + strings[i+1];
  }
  return result;
}

function render(template, element) {
  element.innerHTML = template;
}

With this implementation, the example code from the prompt should work as expected. Note that the html() function simply concatenates the strings and interpolated values to form the template, without any processing or escaping. The render() function simply sets the innerHTML property of the given element to the template string.

However, this implementation does not include any of the optimization or diffing that lit-html provides for efficient rendering and re-rendering. This is not required for the given problem, but is an important aspect of lit-html for optimizing web application performance.
