web.workers.WorkerGlobalScope — clojure-interop/cljs-web-api 1.0.9

The WorkerGlobalScope interface of the Web Workers API is an representing the scope of any worker. Workers have no browsing this scope contains the information usually conveyed by web.Window — in this case event handlers, the console or the associated object. Each WorkerGlobalScope has its own event loop.

atob cljs

(atob this encoded-data)

Method.

The WindowOrWorkerGlobalScope.atob() function decodes a string data which has been encoded using base-64 encoding. You can use btoa() method to encode and transmit data which may otherwise communication problems, then transmit it and use the atob() method decode the data again. For example, you can encode, transmit, decode control characters such as ASCII values 0 through 31.

var decodedData = scope.atob(encodedData);
