> Javascript proponents say the ability to mix and match is its strongest feature, but to me the analysis paralysis of having to stop and shop for a library that does X (and will only do X) is a total productivity killer.

If you can settle on a good enough batteries-included framework without analysis paralysis, you can make the individual as-needed decisions about libraries without it. It's not a problem of a higher order.

If anything, it's lower-pressure, because the cost of a wrong choice is much smaller.
