Benchmark

Simple (and quite complex) operations are currently ~2x faster in jstr than in similar tools such as jq.nodearrow-up-right:

hyperfine --warmup 3 \
  "cat tmp/users.json | jqn 'filter(has(\"email\")) | groupBy(flow(get(\"email\"), split(\"@\"), get(1)))'" \
  "cat tmp/users.json | jstr -i \"flow(A.filter(D.get('email')), A.groupBy(flow(D.get('email'), S.split('@'), A.get(1))))\""
