propertySymbols

NPM version Build Status Coverage Status

Return an array of an object's own symbol properties.

Installation

npm install @stdlib/utils-property-symbols

Usage

var propertySymbols = require( '@stdlib/utils-property-symbols' );

propertySymbols( obj )

Returns an array of an object's own symbol.

var symbols = propertySymbols( {} );

Notes

  • In contrast to the built-in Object.getOwnPropertySymbols(), if provided null or undefined, the function returns an empty array, rather than throwing an error.

Examples

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

function Foo() {
    if ( hasSymbolSupport() ) {
        this[ Symbol( 'beep' ) ] = 'boop';
    }
    return this;
}

Foo.prototype.foo = 'bar';

var obj = new Foo();
var symbols = propertySymbols( obj );

console.log( symbols );
