Helper functions that make writing callbacks for JS libraries in purescript easier.
A lot of JS libraries allow callback actions to be defined, such as in response
to click events, etc. These are effectful functions that accept input and
perform some kind of action (e.g. update the DOM, send a message, whatever).
This library defines purescript types for these kinds of callbacks. JS library
callbacks that are not effectful can be handled with the FnX types in the
Data.Function module of the prelude.
See the doc for full list of functions.
Each CallbackX type is analogous to the FnX types of the prelude. The
callbackX functions are analogous to the mkFnX functions of the prelude.
callbackX_ functions can be used to ignore the input arguments of the
callback and run the effect.
