  8. Determine if the JS environment has Symbol support. Supports spec, or shams.
  9. ## Example
  10. ```js
  11. var hasSymbols = require('has-symbols');
  12. hasSymbols() === true; // if the environment has native Symbol support. Not polyfillable, not forgeable.
  13. var hasSymbolsKinda = require('has-symbols/shams');
  14. hasSymbolsKinda() === true; // if the environment has a Symbol sham that mostly follows the spec.
  15. ```
