How can JavaScript be leveraged to improve user experience and avoid page reloads when performing calculations on a webpage?

To improve user experience and avoid page reloads when performing calculations on a webpage, JavaScript can be leveraged to handle the calculations dynamically on the client-side. This allows for instant feedback to the user without needing to reload the entire page. ```html <!DOCTYPE html> <html> <head> <title>Dynamic Calculation Example</title> <script> function calculate() { var num1 = parseFloat(document.getElementById('num1').value); var num2 = parseFloat(document.getElementById('num2').value); var result = num1 + num2; document.getElementById('result').innerHTML = result; } </script> </head> <body> <input type="text" id="num1" placeholder="Enter a number"> + <input type="text" id="num2" placeholder="Enter another number"> <button onclick="calculate()">Calculate</button> <p>Result: <span id="result"></span></p> </body> </html> ```
