Currying

Currying is the process of transforming a function that takes multiple arguments into a series of functions that each take a single argument.

Example

function add(a) {
    return function(b) {
        return a + b;
    };
}

const addFive = add(5);
console.log(addFive(10)); // Output: 15

Explanation: In this example, the add function returns another function that takes a single argument. Currying is useful for creating more flexible and reusable functions.

Application: Currying is often used in functional programming to create more modular and maintainable code.
