“It’s uncommon to have a programming language
wonk who can speak in such comfortable and friendly
language as David does. His walk through the syntax and
semantics of JavaScript is both charming and hugely
insightful; reminders of gotchas complement realistic
use cases, paced at a comfortable curve. You’ll find
when you finish the book that you’ve gained a strong and
comprehensive sense of mastery.”
—Paul Irish,
developer advocate, Google Chrome
“This
is not a book for those looking for shortcuts; rather it
is hard-won experience distilled into a guided tour.
It’s one of the few books on JS that I’ll recommend
without hesitation.”
—Alex Russell, TC39
member, software engineer, Google
