# get type()

## ​`TypeError.prototype.type`

The [`get`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/get) accessor obtains the type of generic type variable [`Type`](/draft-5/typeerror/generic-type-variables.md#typeerror-less-than-id-type-greater-than-1) that causes an error to be thrown(or not thrown) if set, otherwise returns [`undefined`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/undefined).

{% code title="type-error.class.ts" %}

```typescript
public get type(): Type | undefined {
  return this.#type;
}
```

{% endcode %}
