// Warning: Blob arrayBuffer() method appeared in the major web browser around 2019-2020 (in Deno v1.0 (2020), in Node.js v15.7.0 (2021)).

const toArray = async (blob) => new Uint8Array(await blob.arrayBuffer());


// Usage example (in async logic):

const blob = ...;                   // Blob object
const array = await toArray(blob);  // Uint8Array object

console.log(`array.length=${array.length}`);
console.log(`array[0]=${array[0]}`);
console.log(`array[1]=${array[1]}`);
console.log(`array[2]=${array[2]}`);
console.log(`...`);
