Oooh! A good question. I've done a fair bit of web development in my time, so I think the earliest completion I did was a small HTML (basic) site that I did for a local community group. I was around about 13 when this was completed I think.
At what age did you manage to complete your very first project, regardless of how small it was (either a personal site or blog or forum etc.)? Do you think you could have done it earlier than that?
Probably 7 or 8. I programmed a console print line. #Genius
