+#### ToStringTagSymbol
+
+To string tag [`symbol`][mdn-symbol] which is used to customize the default string description of an object.

+
+## Notes
+
+-   The [symbol][mdn-symbol] is only supported in environments which support [symbols][mdn-symbol]. In non-supporting environments, the value is `null`.
+-   When an object has a property keyed by `[ToStringTagSymbol]` whose value is a string, that string is used as the "tag" in the object's default string description; e.g., `Object.prototype.toString.call( obj )` returns `'[object <tag>]'`.
