[symmet]

There are some points that I'd agree with in this post, but the framing is all wrong. The author begins the article saying that abstractions are fast (the DOM) and ends the article saying that abstractions are slow (jQuery).

The native vs web argument has been beaten to death. It comes down to this: there is no perfect solution and everything has trade-offs (speed, quality, and cost). Use your brain and pick the solution that works best for the problem you are trying to solve. As much as web apps have replaced many things that may have previously been implemented as native apps on the desktop, there is still native development being done.
