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.
The console read-only property of the WorkerGlobalScope interface returns a Console object providing access to the browser console for the worker.
Syntax
var consoleObj = self.console;
Value
A Console object.
Example
This property allows you to have access to a browser console for debugging purposes, inside a worker. So for example you could call
console.log('test');
inside a worker (which would basically be the equivalent of self.console.log('test');, as these are being called on the worker scope, which can be referenced with WorkerGlobalScope.self), to return a test message out to the browser console.
If you are calling console.log() from a DedicatedWorkerGlobalScope or other worker scope that acts on a single loaded window, that tab's web console will receive the logs. However, If you are calling console.log() from a SharedWorkerGlobalScope, the global browser console will receive the logs.
