Resource summary

Haskell - Higher order functions
  1. Are functions that can take functions as parameters and return functions as return values
    1. Curried functions
      1. Recursion
        1. The function in Haskell officially only takes one parameter
          1. Functional programming uses higher order functions to abstract away common patterns
            1. Maps
              1. Filters
                1. Equivalent of applying several predicates in a list comprehension is either filtering something several times
                2. Lambdas
                  1. Are anonymous functions that are used because we need some functions only once
                    1. Lambdas are expressions
                    2. Also can match with patterns
                    3. Normally surrounded by parentheses
                      1. Folds
                        1. They reduce the list to some single value
                          1. Binary function
                            1. Starting value
                              1. Can be used to implement any function where you traverse a list once
                              2. Sacns
                                1. Scans are used to monitor the progression of a function that can be implemented as a fold
                                2. Function application
                                  1. Function composition
