判断是否有问题

if (key === "length" && isArray(target)) {
depsMap.forEach((dep, key) => {
if (key === "length" || key >= newValue) {
deps.push(dep);
}
});
switch (type) {
case TriggerOpTypes.ADD:
if (isArray(target) && isIntegerKey(key)) {
deps.push(depsMap.get("length"));
}
}
}

key === "length" && isArray(target) key 一定是字符串类型，那么forEach 里面的大于号需要判断吗
