WorkerGlobalScope: dump() method

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The WorkerGlobalScope.dump() method logs messages to the browser's standard output (stdout). If the browser was started from a terminal, output sent to dump() will appear in the terminal. This is the same as Window.dump(), but for workers.

Output from dump() is not sent to the browser's developer tools console. To log to the developer tools console, use console.log().
