Knowing how to create variables, use strings, and display output is the foundation of programming in JavaScript.

1

Create a variable with a name

Create a variable called userName and set it to the string "Alice".

Javascript

// Your code here
// Create a variable called userName and set it to "Alice"

Need a hint?

Use const to create a variable and assign the value "Alice" to userName.

2

Create a greeting message

Create a variable called greeting and set it to the string `Hello, ${userName}!` using a template literal.

Javascript

const userName = "Alice";
// Your code here
// Create a variable called greeting using a template literal with userName

Need a hint?

Use backticks ` and ${} to insert the variable userName inside the string.

3

Display the greeting message

Use console.log to display the value of the variable greeting.

Javascript

const userName = "Alice";
const greeting = `Hello, ${userName}!`;
// Your code here
// Use console.log to show greeting

Need a hint?

Use console.log(greeting); to print the greeting message to the console.

4

Run the program to see the greeting

Run the program and make sure the output is exactly Hello, Alice!.

Javascript

const userName = "Alice";
const greeting = `Hello, ${userName}!`;
console.log(greeting);
// Run the program to see the output

Need a hint?

Check the console output to see the greeting message.
