One final legal statement in JavaScript is the empty statement. It
looks like this:
Executing the empty statement obviously has no effect and
performs no action. You might think that there would be little
reason to ever use such a statement, but it turns out that the
empty statement is occasionally useful when you want to create a
loop that has an empty body. For example:
// initialize an array a
for(i=0; i < a.length; a[i++] =index.html 0) ;
To make your code clear, it can be useful to comment your empty
statements as such:
for(i=0; i < a.length; a[i++] =index.html 0) /* empty */ ;
