Similarly, I've always liked javascript's dynamic and flexible nature, especially for ui programming where requirements evolve quickly and dramatically. But now that I've got a big redux app that is on a pretty steady course, I'm starting to see the value that static types would bring. A lot of the mental overhead of working with the codebase now consists of remembering the exact shape of all the data, which properties are defined on which actions, etc. Before too long I'm going to have to give Typescript, Flow, or something along those lines a serious look just for the sake of having it all defined in one place.

I've been singing the praises of Typescript since the first day I started playing with it. Easing into it from a JS codebase is pleasant enough, but greenfield development with typing everywhere is incredible. I highly encourage checking it out sooner rather than later.
