Flow is a static type checker for JavaScript that allows you to add type checking across the codebase incrementally. Unlike Typescript, which is a different language, Flow can be added incrementally to an existing JavaScript codebase supporting the 5th, 6th and 7th editions of ECMAScript. We suggest adding Flow to your continuous integration pipeline, starting with the code that concerns you most. Flow adds to the clarity of the code, increases the reliability of refactoring and catches type-related bugs early during the build.
