Ranked in these QuestionsQuestion Ranking
Pros
Pro Fast to get results
Pro Cross-platform
Inside LiveCode's IDE you can build for OSX, Linux and Windows, and (making use of Xcode and the Android SDK) for iOS and Android too
Pro Extremely simple to get started
Single-click install of entire development environment, and all-in-one IDE makes it easy to go from visually layout out a user interface to writing code to power it to creating your own single-file applications.
Pro GUI-driven development
In LiveCode, you start by dropping GUI elements into place, then add the code that makes them function. This lets beginners see visual results right away, which is often more exciting (especially for young students). It also lets you focus on the user interaction before you get into the nitty-gritty of code implementation.
Pro Approachable yet capable language
Pro Highest ROI compared to other popular cross-platform development tools
Fluid production - from prototyping to delivery in one toolkit. With a high-level language that includes GUI controls as native elements, code more directly expresses the end-user experience. And the platform coverage is awesome, nearly unmatched.
Pro Online IDE
You can use the development environment without installation in your browser and share your programs via the Google Drive integration.
Pro Designed for education
A primary goal of Pyret is to be an excellent choice for a first programming language. This heavily influences the development of the language. For example: if it's felt that some aspect of the language could be made better for the language's users, The development team won't hesitate about implementing breaking (non backwards compatible) changes into Pyret for the greater good of the language. This makes Pyret an impressively "wart free" programming language.
Cons
Con fringe use
Con Poor ecosystem
Not a mainstream programming language.
Con Missing IDE features
For example: content assist, go to declaration, etc.
