Currying and partial application

Currying and partial application are techniques that are used in functional programming to transform functions, but they differ in their approach and application.

Currying

Definition: Currying is a process in which a function that takes multiple arguments is transformed into a sequence of functions, each taking a single argument.

Resulting function: The resulting curried function returns a new function with each invocation, expecting one argument at a time until all the original arguments are supplied.

Here’s an example:

// Curried functionFunc<int, Func<int, int>> addCurried = x => y => x + y;
// Usage
var addWith5 = addCurried(5);
int result = addWith5(3); // Result: 8

Partial application

Definition: Partial application involves fixing a certain number of arguments of a function, creating a new function with fewer parameters.

Resulting function: The resulting partially applied function can be invoked...
