Encode array contents with base64

Question

I want to encode my array contents with base64 if possible in javascript (and then decode later).

Example:

var array = ["stack", "overflow"]
// base64.encode(array)

a simple google search would have yielded this exact page: https://developer.mozilla.org/en-US/docs/Glossary/Base64 — Zachucks, Aug 28 '20 at 13:50

In order to use the well-known function btoa, you'll first have to convert your array to string, in such a way that you can reverse the operation. JSON would be the string format to go for.

So to encode do:

base64 = btoa(JSON.stringify(array))

To decode do:

JSON.parse(atob(base64))
