bytes(): Promise<Uint8Array>
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.
slice(start: number, end: number, contentType: string): Blob
The slice() method of the Blob interface creates and returns a new Blob object which contains data from a subset of the blob on which it's called.
start

contentType
stream(): ReadableStream<Uint8Array>

text(): Promise
The text() method of the string containing the contents of the blob, interpreted as UTF-8.
