Currying

Currying transforms a function that takes multiple arguments into a chain of functions that each take a single argument. Think of it like ordering at a customizable sandwich shop: first you choose the bread, then the protein, then the sauce — each choice narrows down the final result. Currying enables partial application, where you fix some arguments upfront and get back a specialized function ready for the remaining ones.

Use Cases

•Building configurable API request functions where base URL and headers are fixed upfront
•Creating families of validators or formatters that share a common configuration
•Point-free composition in data pipelines where each stage expects a single argument
•Generating event handlers in UI frameworks with pre-bound context or identifiers
