I’ve been front ending for about three years now and I learned a lot on the way. I had the opportunity to work on big sites and I think I’ve reached a good level. Now I want to go for the next step and I don’t know how to do it. Do you suggest to learn by doing (the stuff I do for my job and personal experiments)? Read books? Subscribe to treehouse or others (which one is the best?)? All of the above? Others?
I’m really interested in opinions about treehouse and similar services as they look great but cost a lot (250 a year). Do they really help?
