JavaScript push()

Example

Add new elements to the end of an array, and return the new length: <script type="text/javascript"> var fruits = ["Banana", "Orange", "Apple", "Mango"]; document.write(fruits.push("Kiwi") + "<br />");//返回数组长度，5 document.write(fruits.push("Lemon","Pineapple") + "<br />");//返回数组最末位的值：7 document.write(fruits); </script> The output of the code above will be: 5 7 Banana,Orange,Apple,Mango,Kiwi,Lemon,Pineapple
