It's important to focus on data structures, since getting your data right is step 1 to great Haskell code.

There are three basic flavors to the data structures

API design


Impacts: undefined, infinite structures, performance, memory usage.

Some caveats

There are also ByteString and Text builders for efficient construction.

We'll come back to this quiz after we explore the data types in more detail.
