JavaScript push function is used to add an item at the end to array. We have an array with four element a,b,c and d. arr.push("e","f") will add e and f at the end of array. See the code snippet:
<!DOCTYPE html>
<html>
<head>
<title>Welcome to LearnKode - A code learning platform</title>
</head>
<body>
<button onclick="addElement()">Add new element</button>
<p id="sample"></p>
<script>
var arr= ['a', 'b','c','d'];
document.getElementById("sample").innerHTML = arr;
function addElement() {
arr.push("e","f");
document.getElementById("sample").innerHTML = arr;
}
</script>
</body>
</html>
