网络工作者中的微秒或至少亚毫秒计时？

Question

There are libraries for high precision timers in node.js and there is the window.performance.now() for the main thread https://stackoverflow.com/a/21120901/1056563 . Is there anything for web-workers (which do not have access to window or the DOM )?

Answer 1

There's a performance property on WorkerGlobalScope . It's not super-widely supported, but then again neither are web workers.

Specifically, .now() is (apparently) available to web workers, if that's all you need.
