This throws me back to my junior days (2008~) where i had a heated discussion with my technical lead, to add jQuery to a project.
His argument was that the size of minified library(40kb) would add too much overhead to the loading time of the page.
He then, promptly spent a full week trying to code an ajax call and testing its support on different browsers and ultimately failed to make it work on Internet explorer 5.
jQuery solves many headaches back then, and yes he finally added the library to the project.
Yeah people forget this a lot, browsers used to largely disagree with each other, and jQuery was the only sensible glue that could hold a codebase together in that regard
