Accessing Nested Arrays

Accessing Nested Arrays

Accessing elements within an array using bracket notation []

var fruitBasket = ['apple', 'banana' 'orange', 'melon'];
var favoriteFruit = fruitBasket[2];
  
console.log(favoriteFruit) // 'orange'

In this example, our favourite fruit is 'orange' which is at index 2 in the fruitBasket array. Using braket notation, we assign index 2 of the fruitBasket array to favoriteFruit. This makes favoriteFruit equal to 'orange'.

Accessing objects within arrays using braket [] and dot . notation

var garage = [
  {
    type: 'car',
    color: 'red',
    make: 'Ford'
  },
  {
    type: 'motorbike',
    color: 'black',
    make: 'Yamaha'
  },
  {
    type: 'bus',
    color: 'yellow',
    make: 'Blue Bird'
  }
];

var busColor = garage[2].color; // 'yellow'

Solution:

// Setup
var myPlants = [
  { 
    type: "flowers",
    list: [
      "rose",
      "tulip",
      "dandelion"
    ]
  },
  {
    type: "trees",
    list: [
      "fir",
      "pine",
      "birch"
    ]
  }  
];

// Only change code below this line

var secondTree = myPlants[1].list[1];
