URL Encoding Explained

URL encoding (also called percent-encoding) converts characters that are not allowed in a URL into a format that can be safely transmitted. Each character is replaced by a percent sign (%) followed by two hexadecimal digits.

When to Use URL Encoding

Query string parameters containing special characters
Form data sent via GET requests
Passing URLs as parameters inside other URLs
API request building with user-provided input

Encode vs Encode Component

encodeURI encodes a full URL, preserving characters like : / ? # = &. encodeURIComponent encodes everything including those characters — ideal for encoding individual query parameter values.
