I'm often surprised at the number of JS experts who struggle with the basics of the browser API. Instead of reasoning through the problem, many will reach for a framework or library.

At least historically it used to be the case that you don't ever want to use the browser API directly for compatibility reasons but always through some library that will be a do-nothing-wrapper in some cases but do a bunch of weird stuff for older browsers. And traditions are sticky.

Especially with the MDN, an amazing resource.
