Addition for a Code Playground

[hollermay]

I believe it should have a playground to code same we have coding playground at websites to test tools or any programming language and if we add some basic code to execute will also be a good way to create engagement with suggestion codes below the playground or at a sidebar.

@hollermay This seems to be a nice feature, but users can also use Go Playground.
We can continue this discussion in the website repo where it will be suitable!
