FreeCodeCamp.com - Basic JavaSript - Accessing Nested Arrays
Link to FreeCodeCamp
As we have seen in earlier examples, objects can contain both nested objects and nested arrays. Similar to accessing nested objects, Array bracket notation can be chained to access nested arrays.
Here is an example of how to access a nested array:
var ourPets = [
{
animalType: "cat",
names: [
"Meowzer",
"Fluffy",
"Kit-Cat"
]
},
{
animalType: "dog",
names: [
"Spot",
"Bowser",
"Frankie"
]
}
];
ourPets[0].names[1]; // "Fluffy"
ourPets[1].names[0]; // "Spot"
Instructions
Retrieve the second tree from the variable
myPlants
using object dot and array bracket notation.
Sollution
// 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]; // Change this line
