oop-to-fp-refactor

Refactor TypeScript OOP code to functional programming by replacing classes and constructors with pure functions, converting public methods to exported constant functions, and moving private methods to file scope.

Converting class instance state to pure function arguments requires replacing internal instance members with explicit parameter passing, ensuring stateless execution while preserving the original runtime behavior.

Update dependency injection when rewriting OOP TypeScript to FP by replacing instantiated class factories with singleton tools and adjusting imports to consume pure functional equivalents.

Rewrite CLI command implementations from classes to pure functions by discovering explicit entry points, removing inheritance, and mapping factory patterns to modular function exports.

Functional refactoring preserves the exported API of the original TypeScript code by matching the original usage signatures while replacing the underlying class constructs with trimmed functional equivalents.

Avoid functional programming refactoring for TypeScript code heavily reliant on complex inheritance hierarchies or polymorphic behaviors where mapping to pure functions would obscure logic and reduce clarity.
