Earlier quoted context omitted.
While this is true, and I love JQuery, there's a significant number of JavaScript programmers who do say that JQuery is bloated and slow and old and you shouldn't use it. http://youmightnotneedjquery.com/ and all that. Even if it's not actually true (as you've said, it literally is not bloated wrt filesize) people still think it's true.
Your link explicitely says "you MIGHT not need jQuery", there's nothing wrong about that, quite often you actually don't need it at all. It doesn't say "never use jQuery"
If you have limited time use it, but you'll spend more time later trying to remove it again. Building and then marketing a library that lists jquery as a dependency is somewhat of a blight these days, isn't it?
