How do you properly encode a value to be part of an HTTP POST body? or What’s the best way to encode

I’ve been burned by this before lol. If you’re working with form data, yeah, URL encoding is your friend. But for APIs, JSON.stringify() is cleaner.

Pro tip: escape quotes and backslashes if you’re building the JSON manually. Some frameworks are picky about that.

Also, Chrome DevTools lets you inspect the raw POST body—super handy for debugging.
