How can I set advanced headers in a TypeScript fetch API request?

You can set advanced headers by creating a Headers object and passing it to the fetch function. Here's an example:

Can you show me a code snippet for that?

Sure! Here's a simple example:

const headers = new Headers();
headers.append('Authorization', 'Bearer your_token');
headers.append('Content-Type', 'application/json');

fetch('https://api.example.com/data', {
  method: 'GET',
  headers: headers
})
.then(response => response.json())
.then(data => console.log(data));

What if I need to set custom headers?

You can add custom headers in the same way. Just use the append method on the Headers object to include your custom headers.
