Tell about your experience with REST API. List HTTP methods and response codes.

REST API is an architectural style for interaction between client and server via HTTP.

Main HTTP methods:

• GET — retrieve data from the server.
• POST — create a new resource.
• PUT — update an existing resource (replace).
• PATCH — partially update a resource.
• DELETE — delete a resource.
• OPTIONS — get supported methods from the server.

Main response codes:

• 200 OK — request successfully completed.
• 201 Created — resource successfully created (usually after POST).
• 204 No Content — request successful, but no response body (e.g., after DELETE).
• 400 Bad Request — client error, invalid request.
• 401 Unauthorized — authentication required.
• 403 Forbidden — access denied.
• 404 Not Found — resource not found.
• 500 Internal Server Error — server error.

Experience with REST API includes:

• Formulating requests with correct methods and headers.
• Handling responses and errors.
• Authentication (e.g., via tokens).
• Working with pagination, filtering, and sorting data.

Example of a request to get a list of users:

fetch('https://api.example.com/users', {
  method: 'GET',
  headers: {
    'Authorization': 'Bearer token123',
    'Accept': 'application/json'
  }
})
.then(response => {
  if (!response.ok) throw new Error(response.status);
  return response.json();
})
.then(data => console.log(data))
.catch(error => console.error('Error:', error));
