Interesting you should say that. I wrote a Reddit comment about a year ago listing reasons why I generally advise against use of Immutable.js, and the "infectious" API is exactly one of the reasons that I listed ( https://www.reddit.com/r/javascript/comments/4rcqpx/dan_abramov_redux_is_not_an_architecture_or/d51g4k4?context=3 https://www.reddit.com/r/javascript/comments/4rcqpx/dan_abra... ). Also worth noting that if you are going to do Immutable -> POJO conversions, you should avoid using `toJS()` as much as possible. The conversion process is expensive, _and_ it always creates new object references. Either use `getIn()`, or use memoized selectors to ensure the conversion only happens when the data actually changed.
