Do–while loop in Javascript - Mini Project: Build & Apply

Using a Do-while Loop in JavaScript

📖 Scenario: You are creating a simple program that counts up from 1 to a certain number. This is like counting steps while walking.

🎯 Goal: You will build a program that uses a do-while loop to count from 1 up to a number you choose, and then show the count.

📋 What You'll Learn

Create a variable called count starting at 1

Create a variable called maxCount set to 5

Use a do-while loop to increase count until it is greater than maxCount

Print the final value of count

💡 Why This Matters

🌍 Real World

Counting steps, retries, or attempts in programs often uses loops like <code>do-while</code> to ensure the action happens at least once.

💼 Career

Understanding <code>do-while</code> loops helps in writing programs that need to repeat tasks until a condition changes, common in many software jobs.

1

Create the starting count variable

Create a variable called count and set it to 1.

Javascript

# Your code here

Need a hint?

Use let to create the variable count and set it to 1.

2

Set the maximum count limit

Create a variable called maxCount and set it to 5.

Javascript

let count = 1;
# Your code here

Need a hint?

Use let to create maxCount and set it to 5.

3

Use a do-while loop to count up

Write a do-while loop that increases count by 1 each time, and continues while count is less than or equal to maxCount.

Javascript

let count = 1;
let maxCount = 5;
# Your code here

Need a hint?

Remember, the do block runs first, then the while checks the condition.

4

Print the final count

Write console.log(count) to display the final value of count.

Javascript

let count = 1;
let maxCount = 5;
do {
    count++;
} while (count <= maxCount);
# Your code here

Need a hint?

Use console.log(count) to show the number after the loop ends.
