In practice, however, most engines use insertion order to sort an `object`'s keys, thus allowing for deterministic return values. </section> <!-- /.notes --> <section class="examples"> ## Examples <!-- eslint no-undef: "error" --> ```javascript var objectEntries = require( '@stdlib/utils/entries' ); var obj = { 'beep': 'boop', 'a': { 'b': 'c' }, 'foo': [ 'bar' ] }; var entries = objectEntries( obj ); // e.g., returns [ ['beep', 'boop'], ['a', {'b':'c'}], ['foo', [ 'bar' ]] ] ``` </section> <!-- /.examples --> <section class="links"> [ecma-262-for-in]: http://www.ecma-international.org/ecma-262/5.1/#sec-12.6.4 </section> <!-- /.links -->
