How to create a function in 'sanctuary'?

[davidchambers]

Hello, @lsby, and welcome to the Sanctuary community. 👋

I noticed that in "sanctuary-def", I can use the function "def" returned by "$ .create" to define a new function.

That's the way to do it. :)

So how do I define my own functions in a "sanctuary"?

Sanctuary itself does not provide this functionality; you need to depend on sanctuary-def. If you are using Sanctuary in your project, depending on sanctuary-def directly will not affect your bundle size as it is already a transitive dependency.

Here is a minimal example:

const $ = require ('sanctuary-def');

const def = $.create ({checkTypes: true, env: $.env});

//    greet :: String -> String
const greet =
def ('greet')
    ({})
    ([$.String, $.String])
    (name => `Hello, ${name}!`);
