Test methodology

What does the Built-in Objects Test measure?

The test runs deterministic construction and usage workloads across classic objects, Map and Set collections, typed arrays and buffers, promises and async work, Proxy and Reflect, Intl formatting, and modern utilities. Its score represents weighted operation throughput.

How to interpret the result

The result reflects how efficiently the JavaScript engine constructs and uses native objects, collections, binary buffers, asynchronous primitives, internationalization, and utility APIs.
