Symbol

Symbol factory.

Usage

var Symbol = require( '@stdlib/symbol/ctor' );

Symbol( [description] )

Returns a Symbol primitive.

var s = Symbol();
// returns <symbol>

To aid debugging, provide a symbol description.

var s = Symbol( 'beep' );
// returns <symbol>

Notes

Unlike conventional constructors, the function does not support the new keyword.
The function is only supported in environments which support symbols. In non-supporting environments, the value is undefined.

Examples

var hasSymbolSupport = require( '@stdlib/assert/has-symbol-support' );
var Symbol = require( '@stdlib/symbol/ctor' );

var s;

if ( hasSymbolSupport() ) {
    s = Symbol( 'beep' );

    // Print the value type:
    console.log( typeof s );
    // => 'symbol'

    // Serialize the symbol as a string:
    console.log( s.toString() );
    // => 'Symbol(beep)'

    // Test symbol equality:
    console.log( s === Symbol( 'beep' ) );
    // => false
} else {
    console.log( 'Environment does not support symbols.' );
}
