Examples

var hasSymbolSupport = require( '@stdlib/assert-has-symbol-support' );
var Symbol = require( '@stdlib/symbol-ctor' );
var enumerablePropertiesIn = require( '@stdlib/utils-enumerable-properties-in' );

var hasSymbols = hasSymbolSupport();

function Foo() {
    this.a = 'b';
    if ( hasSymbols ) {
        this[ Symbol( 'a' ) ] = 'b';
