+
+<p>Method <code>unshift</code> menambahkan nilai yang diberikan ke awal objek array.</p>
+
+<p><code>unshift</code> biasanya generic; method ini bisa berupa {{jsxref("Function.call", "called", "", 1)}} atau {{jsxref("Function.apply", "applied", "", 1)}} ke objek menyerupai array. Objek yang tidak memiliki properti <code>length</code> mencerminkan dari serangkaian urutan, properti numerik berbasis zero kemungkinan tidak berperilaku dengan cara yang berarti.</p>

+<h2 id="Contoh">Contoh</h2>
+
+<pre class="brush: js">var arr = [1, 2];
+
+arr.unshift(0); // result of call is 3, the new array length
+// arr is [0, 1, 2]
+
+arr.unshift(-2, -1); // = 5
+// arr is [-2, -1, 0, 1, 2]
+
+arr.unshift([-3]);
+// arr is [[-3], -2, -1, 0, 1, 2]
