  • value <any> 任何任意的、可克隆的 JavaScript 值都将被克隆并自动传给所有新的 Worker 实例。 如果 value 作为 undefined 传入，则 key 之前设置的任何值都将被删除。

  • key <any> Any arbitrary, cloneable JavaScript value that can be used as a <Map> key.
  • value <any> Any arbitrary, cloneable JavaScript value that will be cloned and passed automatically to all new Worker instances. If value is passed as undefined, any previously set value for the key will be deleted.

The worker.setEnvironmentData() API sets the content of worker.getEnvironmentData() in the current thread and all new Worker instances spawned from the current context.
