jarle Convert an ArrayBuffer to a Uint8Array
A Uint8Array is a typed array, meaning it is a mechanism for viewing the data in an underlying ArrayBuffer.
const buffer = new ArrayBuffer(64);
const arr = new Uint8Array(buffer);
Instances of other typed arrays can be created similarly.
const buffer = new ArrayBuffer(64);
const arr1 = new Uint8Array(buffer);
const arr2 = new Uint16Array(buffer);
const arr3 = new Uint32Array(buffer);
const arr4 = new Float32Array(buffer);
const arr5 = new Float64Array(buffer);
const arr6 = new BigInt64Array(buffer);
const arr7 = new BigUint64Array(buffer);
To create a typed array that only views a portion of the underlying buffer, pass the offset and length to the constructor.
const buffer = new ArrayBuffer(64);
const arr = new Uint8Array(buffer, 0, 16); // view first 16 bytes
