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];
