Flow Declaration Remover

Build a utility that transforms Flow-typed JavaScript by removing type declaration statements while preserving executable code.

Requirements

Create a tool that processes JavaScript source code containing Flow type declarations and outputs clean JavaScript with all declare statements removed.

Core Functionality

Your tool should:

• Accept JavaScript source code as a string input
• Remove all Flow declare statements from the code
• Return the transformed code as a string
• Preserve all executable JavaScript code unchanged

Test Cases

• Given input "declare class Logger { }\nconst x = 5;", the output is "const x = 5;" with whitespace preserved @test
• Given input "declare function process(data: any): number;\nfunction run() { return 1; }", the output contains the run function but no declare statement @test
• Given input "declare var CONFIG: string;\nvar value = 'test';", the output contains only the value variable @test
