The DOM API is clear enough that silly abstractions like "selector engines" are unnecessary.

The C vs. Assembly argument is such a silly non-point; apples and artichokes.

Selector engines are clearly not silly abstractions otherwise all major browsers would not have implemented querySelectorAll.

But since they did, why use jQuery on mobile when 100% of mobile browsers support querySelectorAll?

[mkmcdonald]

…which is a façade for the existing CSS engine. Developers clamoured for it (right or wrong), and it was implemented.

Hilarious that you think that one of the core features of the most successful JS library in history is a "silly abstraction".

And JQuery is much more than just a selector engine.
