Calculator app

Hey Andres,

Great job! 👏

I have an awesome idea to make things more fun and user-friendly. 🤗

Let's add a feature that lets users do calculations using their keyboard. 💻🖱️

Here's how to do it:

1. In your HTML code, for each button, add a data-key attribute with the corresponding keyboard key name (e.g., "1" for number keys, "Backspace" for the delete key).

2. Now, in your JavaScript, add an event listener like this:

// Listen for keyboard input
addEventListener("keydown", (event) => handleKeyboardInput(event))

1. You can choose any name for the function; let's call it handleKeyboardInput. Here's the function with comments to explain:

// Function to handle keyboard input
function handleKeyboardInput(event) {
  // Find the button with the data-key attribute matching the pressed key
  const button = document.querySelector(`[data-key="${event.key}"]`);

  // If the button exists, trigger a click event on it
  if (button) {
    button.click();
  }
}

That's it! 🚀 Happy coding, and enjoy the improved functionality! If you have questions or need more help, feel free to ask. 😊💻🌟
