It is a static type checker, designed to quickly find errors in JavaScript applications. Nothing more, nothing less. It's not a compiler, but a checker. It can work without any type of annotations and it is very good at inferring types. To enable type checking in flow add // @flow at the top of the file. It checks types locally and doesn’t have a language server or type definitions like TypeScript. 2. TypeScript : TypeScript is an open-source object-oriented programming language. It was introduced on October 1st, 2012. It follows JavaScript syntactically but adds more features to it. It is a superset of JavaScript. It is launched and maintained by Microsoft under the license of Apache 2. It does not directly run on the browser and requires a compiler to compile and generate a TypeScript file.
