Prototype is an object-oriented JavaScript framework that eases development of dynamic web applications with class-style OO, Ajax support, and DOM manipulation helpers. It was historically influential but is now in maintenance mode with its last major release in 2015.
Use cases
- simplify ajax requests in legacy web apps
- manipulate the dom with a cleaner api
- write class-based object-oriented javascript
- support old browsers like ie6
- maintain an older rails-era web application
When to choose
- maintaining a legacy codebase already built on Prototype
- needing to support very old browsers
- learning the historical foundations of modern JS frameworks
When to avoid
- starting a new modern web project
- needing a component-based ui framework
- requiring active community support and modern tooling
