getWith takes the name of an attribute and returns a function that extracts the value of that attribute from an object.

getwith_recipe.js

const getWith = (attr) => (object) => object[attr]

/**
 * Examples:
 */
const inventory = {
  apples: 0,
  oranges: 144,
  eggs: 36
};

getWith('oranges')(inventory);
  //=> 144

// Combined with mapWith:

const inventories = [
  { apples: 0, oranges: 144, eggs: 36 },
  { apples: 240, oranges: 54, eggs: 12 },
  { apples: 24, oranges: 12, eggs: 42 }
];

mapWith(getWith('oranges'))(inventories);
  //=> [ 144, 54, 12 ]

// Much nicer than writing:
mapWith((inventory) => inventory.oranges)(inventories);
  //=> [ 144, 54, 12 ]

// Combined with maybe:

mapWith(maybe(getWith('oranges')))(inventories);
