说明
flow is a static type checker for JavaScript from Facebook. It adds gradual typing through type annotations and inference, catching errors before runtime. The tool runs as a background server for fast incremental checking. Type annotations use a superset of JavaScript syntax, stripped at build time. Flow integrates with editors for real-time type checking and provides detailed error messages with suggested fixes.
