+
+<p>El método <code><strong>Object.entries()</strong></code> devuelve una matriz de pares propios de una propiedad enumerable [key, value] de un objeto dado, en el mismo orden que es proporcionado por {{jsxref("Sentencias/for...in", "for...in")}} (La diferencia es que un bucle for-in enumera las propiedades en la cadena de prototipos).</p>

+<h2 id="Descripción">Descripción</h2>
+
+<p><code>Object.entries()</code> returns an array whose elements are arrays corresponding to the enumerable property <code>[key, value]</code> pairs found directly upon <code>object</code>. The ordering of the properties is the same as that given by looping over the property values of the object manually.</p>
+
+<h2 id="Ejemplos">Ejemplos</h2>
+
+<pre class="brush: js">var obj = { foo: 'bar', baz: 42 };
+console.log(Object.entries(obj)); // [ ['foo', 'bar'], ['baz', 42] ]
+
+// array like object
+var obj = { 0: 'a', 1: 'b', 2: 'c' };
+console.log(Object.entries(obj)); // [ ['0', 'a'], ['1', 'b'], ['2', 'c'] ]
+
+// array like object with random key ordering
+var an_obj = { 100: 'a', 2: 'b', 7: 'c' };
+console.log(Object.entries(an_obj)); // [ ['2', 'b'], ['7', 'c'], ['100', 'a'] ]
+
+// getFoo is property which isn't enumerable
+var my_obj = Object.create({}, { getFoo: { value: function() { return this.foo; } } });
+my_obj.foo = 'bar';
+console.log(Object.entries(my_obj)); // [ ['foo', 'bar'] ]
+
+// non-object argument will be coerced to an object
+console.log(Object.entries('foo')); // [ ['0', 'f'], ['1', 'o'], ['2', 'o'] ]
+
+// iterate through key-value gracefully
+var obj = {a: 5, b: 7, c: 9};
+for (var [key, value] of Object.entries(obj)) {
+    console.log(key + ' ' + value); // "a 5", "b 7", "c 9"
+}
+
+// Or, using array extras
+Object.entries(obj).forEach(([key, value]) =&gt; {
+    console.log(key + ' ' + value); // "a 5", "b 7", "c 9"
+});
+</pre>

+<h3 id="Converting_an_Object_to_a_Map">Converting an <code>Object</code> to a <code>Map</code></h3>
+
+<p>The {{jsxref("Map", "new Map()")}} constructor accepts an iterable of <code>entries</code>. With <code>Object.entries</code>, you can easily convert from {{jsxref("Object")}} to {{jsxref("Map")}}:</p>
+
+<pre class="brush: js">var obj = { foo: 'bar', baz: 42 };
+var map = new Map(Object.entries(obj));
+console.log(map); // Map { foo: "bar", baz: 42 }</pre>
