What are the use cases for atob()
and btoa()
other than when trying to prevent communication problems in information transfer?
I've researched this online, but I didn't find anything other than information transfer communication problems. This is the resource that I found: atob() and btoa()

See what is base 64 encoding used for.
In particular, on the web, base-64 encoding is useful for contexts where binary data is forbidden, which includes much of HTML. For example, if you want to inline a PNG image file into a URL, for use in an <img src>
for example, you can write data:image/png;base64,...
where ...
is the base-64 encoding of the PNG file. btoa
is useful for generating such URLs, like so:
const url = "data:image/png;base64," btoa(pngContent);
