<!DOCTYPE html>
<html lang="en">
        <head>
                <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>
                <link rel="stylesheet" type="text/css" href="css/bootstrap.css"/>
        </head>
<body>
        <nav class="navbar navbar-default">
                <div class="container-fluid">
                        <a class="navbar-brand" href="https://sourcecodester.com">Sourcecodester</a>
                </div>
        </nav>
        <div class="col-md-3"></div>
        <div class="col-md-6 well">
                <h3 class="text-primary">How to Create Random Person Name Generator</h3>
                <hr style="border-top:1px dotted #ccc;"/>
                <div class="col-md-6">

                        <br />
                        <center><button class="btn btn-primary" onclick="generateName()">GENERATE</button></center>
                </div>
        </div>
<script src="script.js"></script>
</body>
</html>

Creating JavaScript Function

This is where the main function of the application is. This code will display a random name of a person when the button is clicked. To do this just copy and write these block of codes inside the text editor and save it as script.js.

function generateName(){
        let firstname = ["Kai", "Eliana", "Jaden", "Ezra", "Luca", "Rowan", "Nova", "Amara", "Aaliyah", "Finn"];
        let lastname= ["Smith", "Johnson", "Williams", "Brown", "Jones", "Garcia", "Miller", "Davis", "Martinez", "Wilson"];
        let rand_first = Math.floor(Math.random()*firstname.length); 
        let rand_last = Math.floor(Math.random()*lastname.length); 
        let result=document.getElementById('result');
        result.removeAttribute('style');
        result.innerHTML= "<div class='alert alert-success' style='height:120px; padding:20px;'><center><h2>"+firstname[rand_first]+" "+lastname[rand_last]+"</h2></center></div>";
        
}

The code above is very simple, we just only create one method called generateName(). This function will display a random name of a person when the trigger by a button. The code is consist of several arrays object that contains the name and lastname of a person. We use the math() function to randomize the array data to get a random name of person.
