An array is written with square brackets. Indexes start at 0, so the first item is fruits[0].
const fruits = ["mango", "banana"];
fruits.push("durian");
console.log(fruits[0]);
console.log(fruits.length);Looping over items
Use for...of to run code once for each item.
for (const fruit of fruits) {
console.log(fruit);
}Code examples
const colors = ["red", "green", "blue"];
console.log(colors[1]);
console.log(colors.length);Expected output
green 3
Common mistakes
Common mistake: Starting to count at 1
The first item is at index 0. colors[3] in a 3-item array is undefined.
