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

URL encoding is fine for simple key-value pairs, but if you’re dealing with complex data, just use JSON. Less hassle.

One thing to watch: spaces and symbols like & or = can mess up URL-encoded strings. Always test edge cases!

If you’re lazy (like me), libraries like Axios handle encoding automatically for JSON payloads.
