WindowBase64
The WindowBase64 helper contains utility methods to convert data to and from base64, a binary-to-text encoding scheme. For example it is used in data URIs.
There is no object of this type, though the context object, either the Window for regular browsing scope, or the WorkerGlobalScope for workers, implements it.
