Interesting issue. Testing this myself, for NodeJS the magic number seem to be 105,193 items that are still spreadable (so the number in this PR is quite a bit too low). I can't find an official reference for this limitation though, as all specs make it seem like the number is infinite. Also, spreading into an array doesn't have the same limitation.

Thank you for checking!
I checked the push method input limitation with simple code with my environment as follows.

Environment:

• MacBook Pro M1 2020
• Memory 16GB
• OS 13.2
• node v16.13.2

result = [];
// uint8 array
arr = new Uint8Array(120633); // OK
// arr = new Uint8Array(120634); // RangeError: Maximum call stack size exceeded
result.push(...arr);

// string array
arr = Array(120633).fill('1234567890'); // OK
// arr = Array(120634).fill('1234567890'); // RangeError: Maximum call stack size exceeded
result.push(...arr);

The input array length max size is 120633 in my env. Not depends on byte size.

BTW, node 32bit stack size is half of 64 bit according to https://stackoverflow.com/a/20748130.
So, I think chunksize is 100,000 / 2 = 50,000 is better for any environment. I'll update the value to 50000.

Hi @yoshitaka-ogata, I've tackled this by switching to a better querying algo in #1349. I've included your test case, so thanks a lot for opening this PR!
