How do you include a JWT in a fetch request?

Tests knowledge of the fetch options object and Bearer scheme syntax. A strong answer sets headers: { Authorization: Bearer <token> } as the second argument and notes fetch does not auto-attach tokens. Red flag: omitting Bearer or hardcoding secrets.
Tests whether you understand fetch's request configuration pattern and standard HTTP auth header formatting. A strong answer shows the second options argument with a headers object containing Authorization: Bearer <token>, explains that fetch requires manual header attachment unlike XMLHttpRequest, and mentions security practices like avoiding token logging. Red flag: omitting the Bearer prefix, placing the token in the URL query string, or failing to mention that tokens must be passed explicitly.
