What is URL encoding?

URL encoding replaces special characters with percent-encoded equivalents (%20 for space, %26 for &) so they can be safely included in URLs without being interpreted as structural characters.

When do I need to URL encode?

Whenever you include user input in a URL, when query parameter values contain special characters, and when URLs contain non-ASCII characters (accented letters, emoji).

What is the difference between encodeURI and encodeURIComponent?

encodeURI preserves URL structural characters (: / ? # @) and is used for complete URLs. encodeURIComponent encodes everything except letters and digits, and is used for individual parameter values.
