Intro to functional programming

Examples used at DUMP internship lecture, demonstrating basic functional programming concepts.

Running the Haskell examples

In order to run the functions defined in Main.hs, install the cabal-install package. After install, Cabal's package index might need an update:

cabal update

Examples can be tested in the Cabal REPL. To start it, run:

cabal repl

You can then invoke the loaded functions within the REPL. For example:

sum [1..10]

To run the tests, call the following function within the Cabal REPL:

quickCheck prop_<test_name>

To run the functions defined in javascript-examples folder, install NodeJS. Spin up the NodeJS interactive REPL with:

node -i

Load the module by executing .load command within the REPL. For example

.load javascript-examples/setState.js

You should be able to see the results of the executed function calls as well as call the defined functions within the REPL! 🎉
