On: You might not need jQuery

[aroman]

That's a really bad analogy.

People don't use Ruby because C's standard library works differently across different platforms.

This isn't about "rewriting jQuery methods with vanilla js". It's about using the built-in, native, vastly more performant methods that come standard on modern browsers.

The analogy is even worse because Ruby changes way faster than C :)

But anyway, writing code in any 'lower' layer is very educational.
