Hadlebars vs. Hogan vs. Mustache vs. jsRender vs Dust vs Underscore

JavaScript performance comparison

Revision 48 of this test case created by Tharani Venkatesan

Info

Illustrate how much time string-based template engines use executing browsers HTML parser.

Optimizing string interpolation performance is focusing to 10% of the problem, not the 90%.
