how to listen to a keypress event in javascript

To listen to a keypress event in JavaScript, you can use the addEventListener() method to attach an event listener to the document object. Here's an example:

index.tsx
document.addEventListener('keypress', (event) => {
  // Your code here
});

In the above code, we are attaching a keypress event listener to the document object. Whenever a key is pressed while the document is in focus, the event listener function will be executed.

Within the event listener function, you can access information about the key that was pressed using the event parameter. For example, you can get the character code of the key with event.keyCode.

index.tsx
document.addEventListener('keypress', (event) => {
  console.log('Key pressed:', event.keyCode);
});

The above code will log the character code of the pressed key to the console.
