A "continue" statement begins the next iteration of the
innermost enclosing <a href="#For_statements">"for" loop</a>
by advancing control to the end of the loop block.
The "for" loop must be within the same function.

<pre class="ebnf">
ContinueStmt = "continue" [ Label ] .

<p>
If there is a label, it must be that of an enclosing
"for" statement, and that is the one whose execution
advances.
