Echo JS 0.11.0

Many of these are effectively built ins for JS... So would be nice to see performance benchmarks of the js-sdsl library vs. using built-in options for similar patterns in practice.

We benchmarked the compiled files with other popular libraries, I think that was what you want to see!

Thanks for your suggestion, we will update its performance test in the next release, and, we will compare the performance with other popular libraries.
