WebWe used the Effect monad to handle a variety of effects: random number generation, exceptions, console IO, mutable state, and DOM manipulation using React. The Effect monad is a fundamental tool in real-world PureScript code. It will be used in the rest of the book to handle side-effects in a number of other use-cases.
