What is the main advantage of using Sinatra?

The main advantage of using the Sinatra framework is its simplicity and ease of use. Sinatra is a lightweight web framework that has a small codebase and a simple API, which makes it easy for developers to learn and use. Sinatra allows developers to build web applications quickly and easily, without the overhead and complexity of larger frameworks like Ruby on Rails. Sinatra also provides a lot of flexibility, allowing developers to choose their own libraries and tools to build their applications. This simplicity and flexibility make Sinatra well-suited for building small to medium-sized web applications and APIs.
