Scratch 1.x
Scratch 1.x was implemented in Squeak Smalltalk. A follow up version of version 1.4 with many performance improvements and rewritten to be Cog compatible s available for Squeak under the name NuScratch. It was funded by the Raspberry Pi Foundation in order that Scratch would be practical on the incredible, cheap, ultra-cool Raspberry Pi SBC. More
Scratch 2
The second version of Scratch from MIT was a rewrite in Flash. This is the version which in use at a large scale currently. Going for Flash was a move from a completely open development system to proprietary system. To further complicate things, Adobe has end-of-lifed Flash and so a further rewrite had to be done. You can find out about this at http://scratch.mit.edu
Scratch 3
Scratch 3 is a rewrite in JavaScript. It is based on a library called 'Scratch Blocks' which is used for other similar applications as well.
