I think it starts to look like HAML / Slim / Jade once you use CoffeeScript. Understandably not for everyone, but I quite like it, and it doesn't mess with your syntax highlighting like JSX does.

  m "body",
    m "input"
    m "button", "Add"
    m "table",
      m "tr",
        m "td",
          m "input[type=checkbox]"
        m "td", "task description"
