jsPerf.app is an online JavaScript performance benchmark test runner & jsperf.com mirror. It is a complete rewrite in homage to the once excellent jsperf.com now with hopefully a more modern & maintainable codebase.
jsperf.com URLs are mirrored at the same path, e.g:
https://jsperf.com/negative-modulo/2
Can be accessed at:
https://jsperf.app/negative-modulo/2
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%.
Added micro-templates by John Resig and xtpl - it's optimized version
