Arrays & Loops (Quick Guide)
An array is a way to store multiple values in a single variable—like a list. Instead of creating many variables, you group related data together.
A loop lets you go through each item in that array one by one. This is useful when you want to process, display, or modify all values without repeating code.
const fruits = ["apple", "banana", "orange"];

for (let i = 0; i < fruits.length; i++) {
  console.log(fruits[i]);
}
This loop goes through the array and prints each fruit.
In short: Arrays store data. Loops help you work through that data efficiently.
