has-symbols 
Determine if the JS environment has Symbol support. Supports spec, or shams.
Example
1var hasSymbols = require('has-symbols'); 2 3hasSymbols() === true; // if the environment has native Symbol support. Not polyfillable, not forgeable. 4 5var hasSymbolsKinda = require('has-symbols/shams'); 6hasSymbolsKinda() === true; // if the environment has a Symbol sham that mostly follows the spec.
Supported Symbol shams
