Use the push() Method

You can simply use the JavaScript push() method to append values to an array.

The following example will show you how to append single or multiple values to an array in JavaScript.

<script>
var persons = ["Harry", "John", "Clark"];
    
// Append a single value to persons array
persons.push("Peter");
    
console.log(persons);
// Prints: ["Harry", "John", "Clark", "Peter"] 
    
// Append multiple values to persons array
persons.push("Rohn", "Alice");
    
console.log(persons);
// Prints: ["Harry", "John", "Clark", "Peter", "Rohn", "Alice"]
    
// Loop through persons array and display all the values
for(var i = 0; i < persons.length; i++){
    document.write("<p>" + persons[i] + "</p>");
}
</script>
