JavaScript Development – Code Example and Performance Insights

JavaScript empowers dynamic, interactive web experiences and is the backbone of modern web development. Below, we provide a concise code example to illustrate JavaScript’s core functionality, followed by a performance benchmark comparing Vanilla JS, jQuery, and a modern framework for a common task.

Code
Benchmark
Examples
<!DOCTYPE html>
<html>
  <body>
    <button onclick="changeText()">Click Me!</button>
    <p id="demo">JavaScript makes web pages interactive.</p>
    <script>
      function changeText() {
        document.getElementById('demo').textContent = 'You clicked the button!';
      }
    </script>
  </body>
</html>
This simple example demonstrates how JavaScript can update page content in real time. When the button is clicked, the text inside the paragraph changes instantly, showcasing JavaScript’s ability to manipulate the DOM and improve user interaction.
Metric Vanilla JS Vue.js
Initial Load Time Fastest Slowest
Memory Usage Lowest Higher
DOM Update Speed Fast Fast 
console.log('JavaScript is running!');
This line outputs a message to the browser console, confirming that JavaScript code is executing as expected.
