# \[Symbol.toStringTag]

## `[Symbol.toStringTag]`

The [`get`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/get) accessor [`toStringTag`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol/toStringTag) of the [`Symbol`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol) changes the default tag `String` of the instance to the custom tag `Wrap`. It can be read by the [`typeOf()`](https://type.angular-package.dev/v/type-draft/helper/typeof) function of [`@angular-package/type`](https://type.angular-package.dev/).
