What are the best practices for using template literals in JavaScript?

Template literals are a powerful feature in JavaScript. Here are some best practices:

1. Use backticks for multi-line strings.
2. Embed expressions using ${} for cleaner code.
3. Avoid complex expressions inside template literals for readability.

Can you give me an example of using template literals?

Sure! Here's a simple example:

const name = 'Alice';
const greeting = `Hello, ${name}! Welcome to the site.`;
console.log(greeting);

This will output: 'Hello, Alice! Welcome to the site.'

What about using template literals for HTML?

Using template literals for HTML can be very useful. For example:

const title = 'My Page';
const html = `<h1>${title}</h1><p>Welcome to my page!</p>`;

This allows you to create dynamic HTML easily.

Are there any performance concerns with template literals?

Generally, template literals are efficient, but if you're concatenating a large number of strings in a loop, consider using an array and joining it for better performance.
