Frequently Asked Questions

What is percent encoding?

It replaces unsafe characters with a '%' followed by two hex digits, e.g., a space becomes %20. This keeps URLs valid.

What is the difference between encodeURI and encodeURIComponent?

encodeURI encodes a full URI but leaves separators like / and ? intact. encodeURIComponent encodes everything, suitable for query parameter values.
