  • What is Duck Typing in TypeScript?

    Duck typing is a common practice in object-oriented programming languages, and TypeScript introduces a powerful feature called type predicates. This article explains the concept of duck typing and highlights its usefulness in handling different types of data. It compares duck typing in dynamic languages like Python with the approach in JavaScript and TypeScript. TypeScript's type predicates allow for more robust error handling and provide type inference benefits. The article also presents an example use case of recursive resolution and suggests using type predicate libraries for convenience.
