I love articles like these for a few reasons. I like to see the approach other developers take to optimization but I also like the blatant discovery related to the overhead of using prebuilt libraries, frameworks, and other what-have-you’s. These tools are life changing, they’re awesome, but we need to keep in mind the overhead they introduce in the big picture. I think it’s important to build things by hand for a number of reasons, and I don’t want to sound like an evil purist of sorts, but sometimes it’s worth it to put in a little extra effort on your own instead of relying on the comfortable code repository you know and love.
