Can i make something on here and share the end result to a friend.

Question

I.e. code out a blog, and share the actual blog outside of the app

Answer 1

Code Playground has a share function which allows you to obtain a sharable link to your code. On the desktop site, you can just copy the link out of your browser tab.
Just make sure you realize that your blog's source code will be exposed. SoloLearn is not web hosting service, but more of a code sharing platform.
