Currying

Currying is a process in programming where a function that takes multiple arguments is transformed into a sequence of functions, each taking a single argument. Instead of calling a function with all its inputs at once, you call it with one input, which returns a new function expecting the next input. This allows for more flexible code reuse and composition. For example, instead of a function that adds two numbers, you create a curried version that you can partially apply, such as setting one number upfront and then applying the second later, enhancing modularity and clarity.
