Array elements are accessed using their index number:
Array indexes start with 0:
[0] is the first array element
[1] is the second
[2] is the third ...
Example
const fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits[0] = "Kiwi"; // Changes the first element of fruits to "Kiwi"
fruits[0] = "Kiwi"; // Changes the first element of fruits to "Kiwi"
The length property provides an easy way to append a new element to an array:
Example
const fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits[fruits.length] = "Kiwi"; // Appends "Kiwi" to fruits
fruits[fruits.length] = "Kiwi"; // Appends "Kiwi" to fruits
