Early this morning, I went to a dance party on a boat; yes, I’m talking about Daybreaker! I had to catch up on sleep afterwards… I have perused some of Shiny’s source code.

Studying reactive programming as I did yesterday makes me feel more connected with all the people who are teaching themselves React, a web framework in JavaScript (JS). I’m not inclined to program in JS again, so it’s good to know that shinyjs exists.

I have painlessly deployed my single-file Shiny app (it’s available here) using shinyapps.io. This is yet another convenience of the RStudio ecosystem. Below is the R command and its stream. Talk about an abstraction!
