Code purpose
- This code performs an asynchronous HTTP request and returns data from the response
- The final returned value is the main result of the function

Key variables and functions
- res is a named value function or class used by the snippet
- data is a named value function or class used by the snippet
- loadUser is a named value function or class used by the snippet

- Network response is used without checking response.ok
- JSON parsing has no error handling path
- Nested property access may fail when an object is undefined

Learning notes
- Detected language JavaScript TypeScript
- Approximate size 5 lines
- Key names res, data, loadUser
