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.

NOTE:
|
|
|
|
Flow does not support 32-bit systems, but there is a commented out patch
|
|
included here that will allow it to build. Note that although `flow`
|
|
will compile and run on a 32-bit system with this patch, it will not pass
|
|
the built-in tests. The patch is included in the hopes that someone brave
|
|
enough will investigate this and help upstream deliver 32-bit support.
