assert(!isArrayBuffer(function* () { yield 42; return Infinity; });
assert(!isArrayBuffer(Symbol('foo')));
assert(!isArrayBuffer(1n));
assert(!isArrayBuffer(Object(1n)));
assert(!isArrayBuffer(new Set()));
assert(!isArrayBuffer(new WeakSet()));
assert(!isArrayBuffer(new Map()));
assert(!isArrayBuffer(new WeakMap()));
assert(!isArrayBuffer(new WeakRef({})));
assert(!isArrayBuffer(new FinalizationRegistry(() => {})));
