This line demonstrates two core features of Angular's templating capabilities:

* a binding, denoted by double-curlies `{{ }}`

* a simple expression `'yet' + '!'` used in this binding.

The binding tells Angular that it should evaluate an expression and insert the result into the

DOM in place of the binding. Rather than a one-time insert, as we'll see in the next steps, a

binding will result in efficient continuous updates whenever the result of the expression

evaluation changes.

{@link guide/expression Angular expression} is a JavaScript-like code snippet that is

evaluated by Angular in the context of the current model scope, rather than within the scope of

the global context (`window`).

As expected, once this template is processed by Angular, the html page contains the text:

"Nothing here yet!".
