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