Frameworks

Ruby on Rails, Node.js, and other libraries are frameworks that require developers know the underlying language such as Ruby or JavaScript.

Examples of frameworks we typically use are:

• Ruby on Rails
• Phoenix (with Elixir)
• React and React Native

A framework is a library that makes performing a particular task in a programming language easier. Like the framework of a house, it is there when we begin programming and is always there giving the program structure and support.

It can be difficult to switch from one framework to another. The more code that's written specifically for Rails, the harder it will be to switch to Django. That would approach "total rewrite" territory.
