What is URL encoding?

URL encoding replaces unsafe characters with percent-encoded values (e.g., space becomes %20). This ensures URLs are transmitted correctly.

What's the difference between encodeURI and encodeURIComponent?

encodeURI encodes a full URL but preserves special characters like ://?#. encodeURIComponent encodes everything, making it suitable for query parameter values.
