function types.isNativeError
Usage in Deno
```typescript import { types } from "node:node__util.d.ts"; ```
isNativeError(object: unknown): object is Error
Returns `true` if the value was returned by the constructor of a [built-in `Error` type](https://tc39.es/ecma262/#sec-error-objects).
```js
console.log(util.types.isNativeError(new Error())); // true
console.log(util.types.isNativeError(new TypeError())); // true
console.log(util.types.isNativeError(new RangeError())); // true
```
Subclasses of the native error types are also native errors:
```js
class MyError extends Error {}
console.log(util.types.isNativeError(new MyError())); // true
```
A value being `instanceof` a native error class is not equivalent to `isNativeError()` returning `true` for that value. `isNativeError()` returns `true` for errors
which come from a different [realm](https://tc39.es/ecma262/#realm) while `instanceof Error` returns `false` for these errors:
```js
import vm from 'node:vm';
const context = vm.createContext({});
const myError = vm.runInContext('new Error()', context);
console.log(util.types.isNativeError(myError)); // true
console.log(myError instanceof Error); // false
```
Conversely, `isNativeError()` returns `false` for all objects which were not
returned by the constructor of a native error. That includes values
which are `instanceof` native errors:
```js
const myError = { __proto__: Error.prototype };
console.log(util.types.isNativeError(myError)); // false
console.log(myError instanceof Error); // true
```
object is Error
