+
+<p>Properti array <code><strong>length</strong></code> merangkai atau mengembalikan angka dari sejumlah elemen pada array. berupa unsigned, 32-bit integer yang selalu lebih besar dari indeks array terbesar atau index array terakhir.</p>
+
+<pre class="brush: js">var items = ["sepatu", "kaos", "baju", "sweater"];
+items.length;
+
+// index terakhir "sweater" 3
+// returns 4</pre>
+
+<h2 id="Deskripsi">Deskripsi</h2>
+
+<p>Nilai properti <code>length</code> berupa integer positif dan nilainya lebih kecil dari 2 sampai 2 pangkat 32 (2<sup>32</sup>).</p>
+
+<p>Anda bisa merangkai properti <code>length</code> untuk memotong array kapanpun. Ketika anda memperpanjang array dengan mengubah properti <code>length</code>, nomor dari elemen sebenarnya tidak bertambah; contoh, jika anda merangkai <code>length</code> ke 3 ketika saat ini adalah 2, array tetap berisi 2 element. Dengan begitu, properti <code>length</code> tidak selalu menunjukkan jumlah angka dari nilai yang didefinisikan pada array. Lihat juga <a href="/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array#Relationship_between_length_and_numerical_properties" title="Relationship between length and numerical properties">Hubungan antara <code>length</code> dan properti numerik</a>.</p>

+
+<h3 id="Iterasi_pada_array">Iterasi pada array</h3>
+
+<p>Pada contoh, <code>numbers</code> array diiterasikan melalui nilai properti array <code>length</code>. Nilai setiap elemen kemudian dikalikan.</p>
+
+<pre class="brush: js">var numbers = [1, 2, 3, 4, 5];
+var length = numbers.length;
+for (var i = 0; i &lt; length; i++) {
+  numbers[i] *= 2;
+}
+// numbers is now [2, 4, 6, 8, 10]
+</pre>
+
+<h3 id="Memendekan_array">Memendekan array</h3>
+
+<p>Pada contoh memendekkan array <code>numbers</code> ke panjang array 3 jika panjang array sebenarnya lebih besar dari 3.</p>
+
+<pre class="brush: js">var numbers = [1,2,3,4,5];
+
+if (numbers.length &gt; 3) {
+  numbers.length = 3;
+}
+
+console.log(numbers); // [1, 2, 3]
+console.log(numbers.length); // 3
