const fs = require("fs");
const dest = new Uint16Array(1073741824);
// dest.byteLength > buffer.kMaxLength
const fd = fs.openSync("./temp.dat", "r");
fs.readSync(fd, dest, 0, dest.byteLength, 0);

throws

RangeError [ERR_OUT_OF_RANGE]: The value of "length" is out of range. It must be >= 0 && <= 2147483648. Received -2147483648

That's because length |= 0 here converts to signed int32.

Since the max TypedArray size in v8 is expanding to MAX_SAFE_INTEGER, switching to Math.round() I think makes sense (vs adding >>> 0, which would only support uint32)? Happy to open a PR if agreed.

(#21994 looks slightly related, but is about bigint position values.)
