Functional Programming Concepts

  1. What is functional programming?

    it’s an approach to coding that treats computations as math-like functions. It emphasizes immutable data, pure functions, and avoiding side effects.

  2. What is a pure function and how do we know if something is a pure function?

    A pure function consistently produces the same output for a given input and doesn’t have side effects. It relies solely on inputs and doesn’t alter external factors.

  3. What are the benefits of a pure function?

    predictability, simplified testing, and secure parallel processing since they don’t rely on shared state.

  4. What is immutability?

    data that can’t be modified after creation, enhancing stability and predictability

  5. What is Referential transparency?

    it allows you to replace a function call with its result without changing a program’s behavior, promoting clarity and simplification

  2. What does the word ‘require’ do?

    require() is used to import external modules into code.

  3. How do we bring another module into the file the we are working in?

    import or require

  4. What do we have to do to make a module available?
