## Limitations
## `Float16Array` limitations (edge cases)
### The `instanceof` operator
Since `Float16Array` is made by inheriting from `Uint16Array`, it doesn't work if the `instanceof` operator is used to detect a `Uint16Array`.
```js
new Uint16Array(10) instanceof Uint16Array; // true
new Float16Array(10) instanceof Uint16Array; // true
```
Actually, I could use `Proxy`'s `getPrototypeOf` handler to trap it, but that would be too complex and have some limitations.
In addition, it is a bad idea to use `instanceof` to detect the type of `TypedArray`, because it can't be used to detect the type of objects from other Realms, such as iframe and vm. It is recommended to use `Object#toString` or `@@toStringTag` for this purpose.
```js
function isUint16Array(target) {
if (target === null || typeof target !== "object") {
return false;
}
return Object.prototype.toString.call(target) === "[object Uint16Array]";
}
```
For Node.js, you can use `util.types.isUint16Array` ([document](https://nodejs.org/api/util.html#util_util_types_isuint16array_value)) instead. `@@toStringTag` seems to be used for [its implementation](https://github.com/nodejs/node/blob/v16.x/lib/internal/util/types.js).
