What is 'final' keyword for?

Hello, everybody!
In I see code like this:

// Update the page size.
final boolean pageSizeChanged = (pageSize != length);
if (pageSizeChanged) {
pageSize = length;

and later

What a reason to use 'final' keyword here? Dos it help to produce
better java script?

Thank you,
