Simplest way to obfuscate and deobfuscate a string in JavaScript

I'm looking for a way to obfuscate and deobfuscate a string in JavaScript; by which I mean encryption and decryption when security is not an issue. Ideally something native to JS (like base64_encode() and base64_decode() in PHP) to turn a string into something else and back again without having to write a function.

Any suggestions welcome!

You can use btoa() and atob(). btoa() is like base64_encode() and atob() like base64_decode().

Here is an example:

btoa('Some text'); // U29tZSB0ZXh0

atob('U29tZSB0ZXh0'); // Some text

Keep in mind that this is not a secure way to keep secrets. Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation.
