To me there is 3 main points:

  - Even if it's JS, just-js make almost no use of dynamic memory allocations.
  - The authors rewrote himself a postgresql driver that support batching request.
  - it wraps high performance c++ libraries

Even if the techempower implementation is far more verbose and complex than mainstream JS framework, the amount of work behind just-js and its preformances are just impressive!
