 This namespace includes objects for unarchiving binary data in popular archive formats (zip, rar, tar) providing unzip, unrar and untar capabilities via JavaScript in the browser. The unarchiving actually happens inside a Web Worker.

 The unarchivers also support streaming, if you are receiving the zipped file from a slow place (a Cloud API, for instance).  For example:
