Are there any methods in JavaScript that could be used to encode and decode a string using base64 encoding?
Some browsers such as Firefox, Chrome, Safari, Opera and IE10+ can handle Base64 natively. Take a look at this Stackoverflow question. It’s using
btoa()andatob()functions.For server-side JavaScript (Node), you can use
Buffers to decode.If you are going for a cross-browser solution, there are existing libraries like CryptoJS or code like:

With the latter, you need to thoroughly test the function for cross browser compatibility. And error has already been reported.
