Scratch is designed to teach computational thinking rather than focus on specific syntax. It was designed specifically to be easy to learn for anyone over the age of 8.
Pro No need to be able to type
Pro Can be used to create games
Pro Highly structured
The language is highly structured. Therefore, it gives you the essentials of how to think like a programmer and teaches you good programming practices from early on, so you could write clean, working and readable code in the future.
Pro Open source
Distributed under the MIT License.
Pro Written in modern C++, is scriptable in Lua
With support for Android, iOS, Linux, Mac OS X and Windows.
Pro Optional FMOD audio engine
Pro Supports Spine
Box2D integrated with Lua bindings.
Con Does not teach you programming
Learning Scratch might help you if you have high difficulty with logical thinking. However, starting with a proper programming language, especially an easy one, will give you the benefits of starting with something like Scratch and everything else.
Con Won't get you a job
Scratch is not a language used in the workplace. Instead it teaches computational thinking, helping to create a foundation to aid in learning other languages.
Con Not as feature-rich as other engines
Con Small community
Being fairly new on the scene, there aren't much of a community to speak of.
