1

Create a greeting message

Create a variable called greeting and set it to the string 'Hello'.

Javascript

// Create a variable called greeting and set it to 'Hello'
// Your code here

Need a hint?

Use const greeting = 'Hello'; to create the variable.

2

Add your name

Create a variable called name and set it to the string 'Alice'.

Javascript

const greeting = 'Hello';
// Create a variable called name and set it to 'Alice'
// Your code here

Need a hint?

Use const name = 'Alice'; to create the variable.

3

Combine greeting and name

Create a variable called message and set it to a template string combining greeting and name with a space in between, like `Hello Alice`.

Javascript

const greeting = 'Hello';
const name = 'Alice';
// Create a variable called message using a template string combining greeting and name
// Your code here

Need a hint?

Use backticks and ${} to insert variables inside the string.

4

Print the message

Use console.log(message) to print the combined message to the console.

Javascript

const greeting = 'Hello';
const name = 'Alice';
const message = `${greeting} ${name}`;
// Print the message to the console
// Your code here

Need a hint?

Use console.log(message); to show the message in the terminal.
