+# ToStringTagSymbol
+
+> To string tag [symbol][mdn-symbol-tostringtag] which is used to customize the string description of an object.
+
+
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var ToStringTagSymbol = require( '@stdlib/symbol/to-string-tag' );
+```
+
+#### ToStringTagSymbol
+
+To string tag [`symbol`][mdn-symbol-tostringtag] which is used to customize the string description of an object.
+
+```javascript
+var s = typeof ToStringTagSymbol;
+// e.g., returns 'symbol'
+```
+
+
+
+
+
+
+
+
+
+## Notes
+
+- The [symbol][mdn-symbol] is only supported in environments which support [symbols][mdn-symbol]. In non-supporting environments, the value is `null`.
+- The `Object.prototype.toString` method uses the `Symbol.toStringTag` property, if present, as the tag in the string representation. For example, an object with `obj[Symbol.toStringTag] = 'Custom'` will return `'[object Custom]'` when `Object.prototype.toString.call(obj)` is invoked.
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var ToStringTagSymbol = require( '@stdlib/symbol/to-string-tag' );
+
+function valueOfCustom() {
+ return 'custom';
+}
+
+var obj = {};
+obj.valueOf = valueOfCustom;
+
+obj[ ToStringTagSymbol ] = 'Custom';
+
+console.log( Object.prototype.toString.call( obj ) );
+// => '[object Custom]'
+
+var arr = [];
+console.log( Object.prototype.toString.call( arr ) );
+// => '[object Array]'
+
+arr[ ToStringTagSymbol ] = 'MyArray';
+console.log( Object.prototype.toString.call( arr ) );
+// => '[object MyArray]'
+```
