I meant Flow: this talk (http://youtu.be/M8x0bc81smU?t=12m41s http://youtu.be/M8x0bc81smU?t=12m41s) from @scale has the best information about Flow so far. So far, it sounds like a linter similar to JSHint as long as the codebase is in ES6, with two ways to use it: - with regular javascript, it is already able to deduce some constraints from the code itself - with additional type annotations (which is part of ES6, so you don't end up with code that only Flow could use), it can test even more things.
