It is specifically written with the intention of being a professional resource for potential and currently practicing front-end developers to equip themselves with learning materials and development tools.
I just downloaded a PDF of this Handbook and am very interested in what it has to say. It is very challenging trying to keep up-to-date with front-end web development because it is changing so fast these days, and I’m not always sure of what information on the internet is trust-worthy. Having this resource to read and refer to is exactly what I’ve been searching for. I’ll be back with some comments about it after I finish reading it.
