Pug
Pug (formerly known as Jade) is a high-performance template engine for Node.js and browsers that simplifies HTML generation by using a clean, whitespace-sensitive syntax. It allows developers to write templates with less code by eliminating angle brackets and closing tags, supporting features like mixins, includes, and inheritance for reusable components. Pug compiles to standard HTML, making it ideal for server-side rendering in web applications.
Developers should learn Pug when building Node.js-based web applications, especially with frameworks like Express.js, as it streamlines HTML creation and improves code readability and maintainability. It's particularly useful for projects requiring dynamic content rendering, such as e-commerce sites or blogs, where template reuse and logic integration are common. Use Pug to reduce boilerplate code and enhance productivity in full-stack JavaScript development.
