Worker

open external class Worker(scriptURL: String, options: WorkerOptions = definedExternally) : EventTarget, AbstractWorker(source)

This Web Workers API interface represents a background task that can be easily created and can send messages back to its creator. Creating a worker is as simple as calling the Worker() constructor and specifying a script to be run in the worker thread.
