我的 2020 年精選:Josh W. Comeau

Josh Comeau has been an inspiration to me, and I can say the JS community in general. He writes very thoughtful articles on his blog, and they are some of the best I read in 2020 because they either helped me stay on top of the latest in JavaScript or helped me learn something new.
