Example

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.

Supported Symbol shams
