Currying

Currying is a functional programming technique where a function with multiple arguments is transformed into a sequence of functions, each taking a single argument. It allows for partial application, enabling developers to create specialized functions by fixing some arguments in advance. This concept is named after mathematician Haskell Curry and is widely used in languages like Haskell, JavaScript, and Scala.

🧊Why learn Currying?

Developers should learn currying to write more modular, reusable, and composable code, especially in functional programming paradigms. It's useful for creating higher-order functions, implementing function composition, and simplifying complex parameter handling in event handlers or configuration settings. For example, in JavaScript, currying can help manage state in React components or build utility functions that accept configuration step-by-step.
