   An introduction to functional programming

   Functional programming is a programming paradigm that emphasizes the application of functions and avoids changing state and mutable data. Core concepts include pure functions, immutability, higher-order functions, and recursion. Benefits of functional programming include easier reasoning about code, testability, and reusability.

   Understanding JavaScript currying

   Currying is a process that transforms a function that takes multiple arguments into a series of functions that each take a single argument. This makes code more flexible and reusable. In JavaScript, currying can be done by creating a curry() function using recursion. Variadic functions, which accept a variable number of arguments, require additional considerations for currying.
