JavaScript

And when is it enough to get by with the prop-types package?
Yes, I know that unlike prop-types, flow checks types at compile time.
But in mastering and using flow is more difficult than the opponent.
I mean, when is it really worth choosing a flow? In what case is flow not just a choice, but, say, a necessity? Should this be determined by the complexity of the application, or by what criteria?
