Frequently Asked Questions
Why do URLs need encoding?
URLs can only contain certain ASCII characters. Special characters like spaces, ampersands and equals signs must be percent-encoded (e.g. space becomes %20) to be safely included in URLs.
What is the difference between encodeURI and encodeURIComponent?
encodeURI encodes a full URL but preserves characters like colons and slashes. encodeURIComponent encodes everything including those characters, making it suitable for query parameter values.
