About URL Encoding

URL encoding (percent-encoding) converts characters into a format that can be safely transmitted over the internet. Special characters are replaced with a percent sign (%) followed by two hexadecimal digits representing the character's ASCII code.

Encoding Methods:

encodeURIComponent: Encodes all characters except: A-Z a-z 0-9 - _ . ! ~ * ' ( )
encodeURI: Preserves URL structure, doesn't encode: : / ? # [ ] @ ! $ & ' ( ) * + , ; =
Form encoding: Spaces become + instead of %20, used in form submissions

Common Use Cases

Query Parameters: Encoding values in URL query strings
API Requests: Passing data in HTTP requests
Path Segments: Encoding URL path components
Form Data: Submitting form data via GET/POST
