Client and Server

The browser (client) asks; a remote computer (server) answers.

An API request is a message from your page to a server. The server sends back a response. No fetch yet — label the parts of a typical HTTP exchange (builds on Phase 13 promises for “later” results).

        Important JavaScript

        // HTTP pieces (conceptual — fetch comes next)
// Request:  method + URL + headers + optional body
// Response: status + headers + body

// GET  /posts/1     → read one resource (usually no body)
// POST /posts       → create (JSON body often)
// PUT  /posts/1     → replace/update
// DELETE /posts/1   → remove
