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.
