The importScripts() method of the WorkerGlobalScope interface synchronously imports one or more scripts into the worker's scope.
Syntax
self.importScripts('foo.js');
self.importScripts('foo.js', 'bar.js', ...);
Parameters
A comma-separated list of DOMString objects representing the scripts to be imported.
Returns
Void.
Example
If you had some functionality written in a separate script called foo.js that you wanted to use inside worker.js, you could import it using the following line:
importScripts('foo.js');
importScripts() and self.importScripts() are effectively equivalent — both represent importScripts() being called from inside the worker's inner scope.
