class Blob

A file-like object of immutable, raw data. Blobs represent data that isn't necessarily in a JavaScript-native format. The File interface is based on Blob, inheriting blob functionality and expanding it to support files on the user's system.

arrayBuffer(): Promise<ArrayBuffer>;
Returns a promise that resolves to the contents of the blob as an ArrayBuffer
bytes(): Promise<Uint8Array<ArrayBufferLike>>;
Returns a promise that resolves to the contents of the blob as a Uint8Array (array of bytes) its the same as new Uint8Array(await blob.arrayBuffer())
formData(): Promise<FormData>;
Read the data from the blob as a FormData object.
This first decodes the data from UTF-8, then parses it as a multipart/form-data body or a application/x-www-form-urlencoded body.
The type property of the blob is used to determine the format of the body.
This is a non-standard addition to the Blob API, to make it conform more closely to the BodyMixin API.
json(): Promise<any>;
Read the data from the blob as a JSON object.
This first decodes the data from UTF-8, then parses it as JSON.
slice(
start?: number,
end?: number,
contentType?: string

stream(): ReadableStream<Uint8Array<ArrayBufferLike>>;
Returns a readable stream of the blob's contents
