Why is creating a Float32Array with an offset that isn't a multiple of the element size not allowed?

Question

I\'d like to read a binary file with a few 32 bit float values at byte offset 31.

Unfortunately, new Float32Array(buffer, 31, 6); does not work. An offs

You can use slice to get a new ArrayBuffer whose contents are a copy of this ArrayBuffer's bytes from begin, inclusive, up to end

const buffer = new ArrayBuffer(250);
const list = buffer.slice(10); // index [11,250]
const nums = new Int32Array(list, 0, 60);
