Flow 和 TypeScript 的区别

1. 流程：
Flow 由 Facebook 开发和维护。它是一个静态类型检查器，旨在快速查找 JavaScript 应用程序中的错误。不多也不少。它不是编译器，而是检查器。它可以在没有任何类型的注释的情况下工作，并且非常擅长推断类型。要启用流中的类型检查，请在文件顶部添加 // @flow。它在本地检查类型并且没有像 TypeScript 这样的语言服务器或类型定义。

2.打字稿：
TypeScript 是一种开源的面向对象的编程语言。它于 2012 年 10 月 1 日推出。它在语法上遵循 JavaScript，但添加了更多功能。它是 JavaScript 的超集。它由 Microsoft 在 Apache 2 许可下发布和维护。它不直接在浏览器上运行，需要编译器来编译和生成 TypeScript 文件。

Flow 和 TypeScript 的区别：

S.No.	FLOW	TYPESCRIPT
1.	It is developed by Facebook in 2014.	It is developed by Microsoft in 2012.
2.	The main features of Flow are Precision, Real-time feedback, Easy to integrate, Reliability, Speed, High throughput, Path sensitivity, Low latency, Type inference, Easily understandable JavaScript patterns.	The main features of Typescript are Compile-time type checking, Enumerated type, Interfaces, Namespaces, Type annotations, Type erasure, Type inference, Generic, Tuples.
3.	Its utility size is 68.4 MB.	Its utility size is 42.4 MB.
4.	It is best choice we are working on React as it is easily integrated with babel and the already present infrastructure.	It is best choice when we are working on Angular 2 or higher versions.
5.	It doesn’t really support encapsulation.	It supports encapsulation with public, private, protected modifiers and readonly since TypeScript 2.0.
6.	It is only supported by React.	It is much better because it support major frontend frameworks like Vue, Angular, and Facebook’s own React.
7.	It support very few library.	It support many library.
8.	Along with the provision of static typing, it also provides us a wide range of inter-procedural analysis and develops an in-depth understanding of our code.	Along with the provision of static typing, it also provides us with great language services and appropriate tooling that includes code refactoring, navigation, and auto-completion.
