What characters does URL encoding escape?

All characters except A-Z, a-z, 0-9, and - _ . ~ are percent-encoded. For example, spaces become %20 and & becomes %26.

What is the difference between encodeURI and encodeURIComponent?

encodeURI preserves URL structure characters like : / ? # while encodeURIComponent encodes everything except unreserved characters. Use encodeURIComponent for individual parameter values.

Why do I need URL encoding?

URLs have special characters with reserved meanings (? starts query, & separates params, = assigns values). Encoding ensures your data does not break the URL structure.
