Beware of Microsoft's jQuery-tmpl templates, if you care about being able to render your views with reasonable performance. You can benchmark 'em yourself here:

TL, Didn't Benchmark: Two orders of magnitude slower (approx) than other engines. On the iPad, for example, jQuery-tmpl was able to render a small template 181 times in a second, whereas Eco, at the other end of the scale, was able to render the same template 11,549 times.
