The task is to perform a push operation without using the push() method with the help of JavaScript. There are two approaches that are discussed below.
Approach 1: Use the length property to insert the element at the end of the array.
Example: This example implements the above approach.
html
<body style="text-align: center;"> <h1 style="color: green;"> neveropen </h1> <h3> Alternatives of push() method in Javascript </h3> <p id="GFG_UP"></p> <button onclick="myGFG()"> Click Here </button> <p id="GFG_DOWN"></p> <script> var arr = ["Element 1", "Element 2", "Element 3", "Element 4"]; var up = document.getElementById("GFG_UP"); up.innerHTML = "Array = [" + arr + "]"; var element = "Element x"; var down = document.getElementById("GFG_DOWN"); function myGFG() { arr[arr.length] = element; down.innerHTML = "Elements of array = [" + arr + "]"; } </script> </body> |
Output:
