Most popular benchmarking tool is http://jsperf.com but doing benchmarks there takes a lot of time, requires module inlining and in general makes it a lot harder to benchmark an actual library or program. Also ideally you would love to see how specific changes affect performance.
node has flame graphs, chrome has profiler probably there's more. I'd love to learn more about how programs can be benchmarked ideally that should be JS engine agnostic
