Why conditional logic is needed in Javascript - See It in Action

Why conditional logic is needed

📖 Scenario: Imagine you are building a simple program that helps a coffee shop decide what message to show customers based on the time of day.

🎯 Goal: You will create a small program that uses conditional logic to show different messages depending on the time.

📋 What You'll Learn

Create a variable to hold the current hour of the day

Create a variable to hold a message

Use conditional logic with if and else to set the message based on the hour

Print the message to the console

💡 Why This Matters

🌍 Real World

Conditional logic helps programs make choices, like showing different messages or taking different actions based on information.

💼 Career

Understanding conditional logic is essential for all programming jobs because it lets software respond to different situations.

1

DATA SETUP: Create a variable for the current hour

Create a variable called currentHour and set it to the number 9.

Javascript

// Create a variable called currentHour and set it to 9
// Your code here

Need a hint?

Use const to create the variable and assign the number 9.

2

CONFIGURATION: Create a variable for the message

Create a variable called message and set it to an empty string "".

Javascript

const currentHour = 9;
// Create a variable called message and set it to an empty string
// Your code here

Need a hint?

Use let because the message will change later.

3

CORE LOGIC: Use conditional logic to set the message

Use if and else statements to set message to "Good morning!" if currentHour is less than 12, otherwise set it to "Good afternoon!".

Javascript

const currentHour = 9;
let message = "";
// Use if and else to set message based on currentHour
// Your code here

Need a hint?

Use if (currentHour < 12) to check the time and set the message accordingly.

4

OUTPUT: Print the message

Write console.log(message) to display the message in the console.

Javascript

const currentHour = 9;
let message = "";
if (currentHour < 12) {
    message = "Good morning!";
} else {
    message = "Good afternoon!";
}
// Print the message to the console
// Your code here

Need a hint?

Use console.log(message) to show the message.
