# Encoding Functions

Built-in functions for encoding and decoding text. They are always available - no import required.

* **URL encoding** - `encodeURIComponent` / `decodeURIComponent` escape and unescape characters that are unsafe in a URL.
* **Base64** - `btoa` / `atob` convert between raw text and Base64.

The pages below cover each pair.
