Using flow or typescript vs prop types

[phuongy]

Any preferences or arguments about this? Prop types are old and terrible. I think going forward we should go to flow or ts. My TS is rusty so someone else might need to start this change, otherwise we people want to use flowtype, happy to start this branch.

I'd lean toward TS simply because I have used that one. I can't say I have had huge issues around typing in a project this size, so I don't have strong feelings either way.

Agreed the project is small enough to not warrant the extra effort. Did anyone want to give this a try, could be a good exercise for anyone wanting to mess with TS / flow.
