What is URL encoding (percent-encoding)?

URL encoding replaces unsafe characters with a % followed by two hex digits. For example, a space becomes %20 and & becomes %26. It's required to safely include special characters in URLs.

What is the difference between encodeURI and encodeURIComponent?

encodeURI encodes a full URL, preserving characters like :, /, ?, and &. encodeURIComponent encodes a single component value (like a query parameter), also encoding those special characters.

When should I URL-encode a string?

Always encode query parameter values before appending them to a URL. Special characters like spaces, &, =, and + would otherwise break the URL structure.
