A template is a piece of code that is used to generate HTML. It is often used to create complex webpages that would otherwise be difficult to create by hand. Templates can include variables, loops, and conditionals to make the code more dynamic and to make it easier to maintain. Templates can also be used to reuse code, saving developers time and effort.

When a template is used, the code is processed by a template engine. The template engine reads the template file and executes the code within it, generating HTML from the template. This HTML is then sent to the browser, which renders it as a webpage.

Second, templates can save time and effort for developers, as they can be reused and modified as needed. Third, templates can provide a consistent look and feel across a website. Finally, templates can be used to generate HTML in a variety of formats, such as HTML, XML, and JSON.

Node.js includes several template engines that can be used to generate HTML. Popular template engines include EJS, Handlebars, and Jade. These engines can be used to render dynamic webpages with Node.js.
