Test methodology
What does the Array Test measure?
The test runs seven repeatable phases: Sieve of Eratosthenes; map, filter, and reduce; sorting; searching; splice and shift; flat and spread; and typed-array work. It counts completed operations and measures elapsed time. The performance score is operation throughput scaled by the test weight.
How to interpret the result
The result reflects JavaScript array-processing throughput across numeric calculations, filtering, sorting, searching, mutations, and typed-array operations.
