+The goal of Flow is to find errors in JavaScript code with little programmer effort.
+Flow relies heavily on type inference to find type errors even when the program has not been annotated
+It precisely tracks the types of variables as they flow through the program.
+
+At the same time, Flow is a gradual type system.
+Any parts of your program that are dynamic in nature can easily bypass the type checker
+so you can mix statically typed code with dynamic code.
+
+Flow also supports a highly expressive type language.
+Flow types can express much more fine-grained distinctions than traditional type systems.
+For example, Flow helps you catch errors involving null, unlike most type systems.
