Python-style kwargs in TypeScript: A Neat Trick for Improved Readability
2025-09-25
This article presents a clever technique to mimic Python's keyword arguments (kwargs) in TypeScript, addressing the readability and maintainability challenges posed by functions with numerous optional parameters. By using an object containing optional parameters as a function argument, developers can clearly specify which parameters to modify without a chain of `undefined` values. This improves code readability and debuggability while preserving TypeScript's type safety. While changes to parameter names might break compatibility, using this within internal functions significantly simplifies code.
