<p>Determine if the JS environment has <code>Symbol.toStringTag</code> support. Supports spec, or shams.</p>

<h3>Example</h3>

<pre><code>
var hasSymbolToStringTag = require('has-tostringtag');

hasSymbolToStringTag() === true; // if the environment has native Symbol.toStringTag support. Not polyfillable, not forgeable.

var hasSymbolToStringTagKinda = require('has-tostringtag/shams');
hasSymbolToStringTagKinda() === true; // if the environment has a Symbol.toStringTag sham that mostly follows the spec.
</code></pre>
