Pug
Pug serves as a template engine designed for both Node.js and browsers, facilitating the dynamic rendering of reusable content. During the compilation phase, Pug translates our template code into HTML. Similar to JavaScript, Pug allows the use of variables, which are later substituted with real values during runtime. The template engine then transforms the template into an HTML file, ready to be rendered on the client side.
Pug boasts numerous robust features, including conditions, loops, includes, and mixins, enabling the dynamic rendering of HTML code based on user input or referenced data. With native support for JavaScript, Pug allows the integration of JavaScript expressions to format HTML code. This approach empowers the reuse of static web pages by incorporating dynamic data seamlessly.
npm install express pug
What are template engines in Express, and why are they used?
A Template Engine simplifies the use of static templates with minimal code. During runtime on the client side, variables in the template are replaced with actual values. These engines help developers create templates for web pages, written in a markup language with placeholders for dynamic content. When rendered, these placeholders are substituted with real data, producing a dynamic document.
We will learn about the following template engines and why they are used:

EJS:
EJS, or Embedded JavaScript Templating, is a templating engine utilized in Node.js. This engine assists in the creation of HTML templates with minimal code, allowing the injection of data into the template on the client side to generate the final HTML output. EJS serves as a straightforward templating language, utilizing plain JavaScript to generate HTML markup. Additionally, it facilitates the embedding of JavaScript into HTML pages. To initiate the use of EJS as a templating engine, installation is required via the provided command.
npm install ejs --save
