## How about key/value pairs?

###

    let fruits = {
      "apples": ['Macoun', 'Empire', 'Honey Crisp', 'Albemarle Pippin'],
      "oranges": ['Naval Orange', 'Tangelo', 'Clementine', 'Valencia Orange']
    }
    /*
    [] square bracket way of accessing values:
    fruits["apples"] is the array of apple varieties
    fruits["oranges"] is the array of orange varieties

    You can also use the .key syntax:
    fruits.apples is the same as fruits["apples"]
    fruits.oranges is the same as fruits["oranges"]

    */

### Getting keys and values through iteration

    let fruits = {
      "apples": ['Macoun', 'Empire', 'Honey Crisp', 'Albemarle Pippin'],
      "oranges": ['Naval Orange', 'Tangelo', 'Clementine', 'Valencia Orange']
    }

    /* iterate through keys */
    console.log("Iterate with: 'for ... in'");
    for (let type in fruits) {
      console.log(type);
    }
    console.log("DONE!");

    /* and you can use values */
    console.log("Iterate with: 'for ... in' for keys and use values");
    for (let type in fruits) {
      console.log(type);
      for (let variety of fruits[type]) {
        console.log(variety)
      }
    }
    console.log("DONE!");
