arraybuffer : true if JSZip can read and generate ArrayBuffer, false otherwise.uint8array : true if JSZip can read and generate Uint8Array, false otherwise.blob : true if JSZip can generate Blob, false otherwise.nodebuffer : true if JSZip can read and generate nodejs Buffer, false otherwise.nodestream : true if JSZip can read and generate nodejs stream, false otherwise.
