I just finished up making a few improvements to sidemail.io docs, and one of the things I added are runnable code examples (Runkit). I borrowed the idea from Stripe, which does the same thing on their landing page. But, I've never seen it used in docs before, and that makes me wonder if it's good DX.
As a developer, would you find it useful when integrating 3rd party API?
PS: runnable examples are only visible on screens wider than 800px, sorry mobile users!
