Blob: bytes() method - Web APIs | MDNBlob: bytes() method
Limited availability
The bytes() method of the Blob interface returns a Promise that resolves with a Uint8Array containing the contents of the blob as an array of bytes.
The method will reject the returned Promise if, for example, the reader used to fetch the blob's data throws an exception.
