JavaScript and Kotlin: Chain Ability

Kotlin could have gone full monad. Full monad. But they chose not to far for the same reason that, you know, C++ is backwards compatible with C. I think they thought it was going to be too big of a shift. It does allow you to chain things together. And then each one can say, oh, if it's null, pass it on. If it's not, unless somebody else deal with it or maybe even include, say, an exception that gets thrown and some kind of error condition.
