At the age of 38, am I too late to change career to front end dev work?

I started my career in IT (and dabbled a bit with what was then basic HTML, CSS and PHP), then worked for c. 10 years in accountancy but have longed to switch careers and work as a front end developer. But I'm worried that with no recent relevant work experience and my age (38), I will not be able to compete with younger folks just coming out of uni/college. Am I basically too late to switch to this particular career? I appreciate any thoughts/advice you might have on this :-)
