                                        nested loops

A for-of loop goes through each element in an array, one by one.

for (const item of array) {
  // code runs for each item
}

The variable (item) gets each value from the array:

const numbers = [10, 20, 30];
for (const num of numbers) {
  console.log(num);
}
// Prints: 10, then 20, then 30

const names = ["Alice", "Bob", "Carol"];
for (const name of names) {
  console.log(name);
}
