md`Let’s also make a handy \`dot\` function that returns the property of an object.`
dot = curry((prop, obj) => obj[prop])

You can now create \`sortedPhone2\` that:
* gets rid of the wrapping and unwrapping and all of the extra fluff;
* boils it down to the essential parts, making it more understandable and maintainable;
* makes it completely data generic.

sortedPhones2 = compose(
map(dot("phone")),
R.sortBy(dot("signup_date"))
