@JsProperty(name="self")
public static @JsNonNull WorkerGlobalScope self()
```
The self read-only property of the WorkerGlobalScope interface returns a reference to the WorkerGlobalScope itself. Most of the time it is a specific scope like DedicatedWorkerGlobalScope, SharedWorkerGlobalScope, or ServiceWorkerGlobalScope.

importScripts
```
public static void importScripts(@Nonnull
                                 java.lang.String... urls)

atob
```
public static @JsNonNull java.lang.String atob(@Nonnull
                                               java.lang.String data)
```
The WindowOrWorkerGlobalScope.atob() function decodes a string of data which has been encoded using Base64 encoding. You can use the btoa() method to encode and transmit data which may otherwise cause communication problems, then transmit it and use the atob() method to decode the data again. For example, you can encode, transmit, and decode control characters such as ASCII values 0 through 31.

                                               java.lang.String data)
```
The WindowOrWorkerGlobalScope.btoa() method creates a Base64-encoded ASCII string from a binary string (i.e., a String object in which each character in the string is treated as a byte of binary data).

The EventTarget.removeEventListener() method removes from the EventTarget an event listener previously registered with EventTarget.addEventListener(). The event listener to be removed is identified using a combination of the event type, the event listener function itself, and various optional options that may affect the matching process; see Matching event listeners for removal
