Partials

Partials are reusable template fragments in web development frameworks that allow developers to break down complex views into smaller, modular components. They enable code reuse, improve maintainability, and help keep templates DRY (Don't Repeat Yourself) by embedding common UI elements across multiple pages. This concept is widely implemented in templating engines and frameworks like Ruby on Rails, Laravel, and Handlebars.

Also known as: Partial templates, Template partials, View partials, Fragments, Include files

Why learn Partials?

Developers should use partials when building web applications with repetitive UI elements, such as headers, footers, navigation bars, or sidebars, to avoid duplicating code and simplify updates. They are essential in MVC (Model-View-Controller) architectures for organizing view logic, enhancing collaboration in teams, and speeding up development by promoting component-based design. For example, in a Rails app, partials help render consistent layouts across different views without rewriting HTML.
