algebraic data type

Front

a type where we specify the shape of each of the elements - make our own data type using the keyword data

Back

pattern matching

Front

specify patterns to which some data should conform and then checking to see if it does and deconstructing the data according to those patterns

Back

Front

Back

ways of testing whether some property or value is true or false - similar to an if statement
