How can I use template literals for multi-line strings in JavaScript?

How can I use template literals for multi-line strings in JavaScript?

You can use backticks (`) to create template literals, which allow for multi-line strings. For example:

const message = `This is a string
that spans multiple lines.`;

This will preserve the line breaks.

Can you show me an example of how it works in a function?

Sure! Here's a function that returns a multi-line string:

function getGreeting(name) {
    return `Hello, ${name}!
Welcome to our website.`;
}

Calling getGreeting('Alice') will return:

Hello, Alice!
Welcome to our website.

What if I want to include variables in my multi-line string?

You can easily include variables using the ${variable} syntax within the backticks. For example:

const user = 'Alice';
const message = `Hello, ${user}!
How are you today?`;

This will output:

Hello, Alice!
How are you today?
