Configuring Fetch Requests with `RequestInit`
`RequestInit` is the options object that customizes a `fetch` call beyond a simple GET. Use it to specify the HTTP method, send a request body, set headers, and control caching. A common footgun is sending a JSON body without setting the `Content-Type` header.
`RequestInit` is the instruction manual for a `fetch` request, letting you customize it beyond a simple GET. This object specifies the HTTP method (like POST), headers, request body, and caching strategy. It's essential for sending data to a server or controlling browser caching. A common footgun is forgetting to `JSON.stringify()` the `body` and set the `Content-Type` header to 'application/json', which servers will often reject or misinterpret.
