What are the best practices for structuring complex HTML content in JavaScript without using PHP includes?

When structuring complex HTML content in JavaScript without using PHP includes, one approach is to use template literals to define the HTML content within your JavaScript code. This allows you to easily create and manipulate HTML elements dynamically. By using template literals, you can keep your HTML content separate from your JavaScript logic, making your code more maintainable and easier to read. ```javascript const complexContent = ` <div> <h1>Hello World</h1> <p>This is a complex HTML content structure.</p> </div> `; document.getElementById('container').innerHTML = complexContent; ```
