Nested loops in Javascript - Mini Project: Build & Apply

Nested loops

📋 What You'll Learn

💡 Why This Matters

🌍 Real World

Nested loops are useful when you want to check every combination of two sets of things, like seating guests at tables or matching products with colors.

💼 Career

Understanding nested loops is important for jobs involving data processing, game development, or any task that requires comparing or combining multiple lists.

1

Create the tables array

Create an array called tables with these exact values: 'Table 1', 'Table 2', and 'Table 3'.

Javascript

// Create the tables array
// Your code here

Need a hint?

Use square brackets [] to create an array and separate values with commas.

2

Create the guests array

Create an array called guests with these exact values: 'Alice', 'Bob', and 'Charlie'.

Javascript

const tables = ['Table 1', 'Table 2', 'Table 3'];
// Create the guests array
// Your code here

Need a hint?

Use the same array syntax as before to create the guests array.

3

Use nested loops to pair guests with tables

Use a nested for loop where the outer loop uses the variable table to go through tables and the inner loop uses the variable guest to go through guests.

Javascript

const tables = ['Table 1', 'Table 2', 'Table 3'];
const guests = ['Alice', 'Bob', 'Charlie'];
// Use nested for loops to pair guests with tables
// Your code here

Need a hint?

Use for (const variable of array) syntax for each loop.

4

Print the seating assignments

Inside the inner loop, print the string `${guest} sits at ${table}` using console.log.

Javascript

const tables = ['Table 1', 'Table 2', 'Table 3'];
const guests = ['Alice', 'Bob', 'Charlie'];

for (const table of tables) {
    for (const guest of guests) {
        // Print the seating assignment
        // Your code here
    }
}

Need a hint?

Use console.log with a template string to print the message.
