@stdlib/utils-entries NPM

Object Entries

Return an array of an object's own enumerable property key-value pairs.

Installation

npm install @stdlib/utils-entries

Usage

var objectEntries = require( '@stdlib/utils-entries' );

objectEntries( obj )

Returns an array of an object's own enumerable property [key, value] pairs.

var obj = {
    'a': 1,
    'b': 2
};

var entries = objectEntries( obj );
// e.g., returns [ ['a', 1], ['b', 2] ]

Notes

Entry order is not guaranteed, as object key enumeration is not specified according to the ECMAScript specification. In practice, however, most engines use insertion order to sort an object's keys, thus allowing for deterministic return values.

Examples

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' ]] ]

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
