In today’s web development industry there is one recurring theme that almost everyone is getting wrong:
“Let’s drop in this 100kb JS library to implement that feature. Just ship one less JPG and we’re set.”
As it turns out, on a Nexus 5, 1MB of ungizipped JS takes up to 2 full seconds just in the parsing phase!
It can’t be stressed enough, it’s not just about the file weight. It really isn’t.
This piece is part of the #ASKTHEINDUSTRY project, a series of daily conversations with the Web Dev industry. You ask, I’ll answer, or find someone who can.
