| Determine if the JS environment has Symbol support. Supports spec, or shams. |
| |
| ## Example |
| |
| ```js |
| var hasSymbols = require('has-symbols'); |
| |
| hasSymbols() === true; // if the environment has native Symbol support. Not polyfillable, not forgeable. |
| |
| var hasSymbolsKinda = require('has-symbols/shams'); |
| hasSymbolsKinda() === true; // if the environment has a Symbol sham that mostly follows the spec. |
| ``` |
| |
