how do i fetch an pi in javascript

To fetch data from an API in JavaScript, you can use the Fetch API. Here's an example:

index.tsx
fetch('https://api.example.com/pi')
  .then(response => response.json())
  .then(data => {
    // Handle the data received from the API
    console.log(data);
  })
  .catch(error => {
    // Handle any errors that occurred during the request
    console.error('Error:', error);
  });

In this example, replace https://api.example.com/pi with the actual URL of the API you want to fetch the PI data from. The fetch function makes a request to the API and returns a Promise. We can then use the .then method to handle the response data.

The response is initially in a JSON format, so we need to call the .json() method on the response to convert it into a JavaScript object. The second .then method is used to access the data retrieved from the API and perform any necessary operations on it.

If an error occurs during the request, the .catch method will be executed, allowing you to handle the error accordingly.

Make sure to test your code in a browser or an environment that supports the Fetch API, as it is not available in all JavaScript environments.

Also, keep in mind that the example assumes the API returns PI data in JSON format. If the API returns data in a different format, you may need to adjust the code accordingly.
