==Features==

The most important features that Snap''!'' offers, but Scratch does not, include:

* expressions using anonymous functions, represented by a block inside a gray ring, having one or more empty slot(s)/argument(s) that are filled by a "higher order function" (the one that is calling the anonymous one). (Their computer-science theoretical basis isare [[first class function]]s, which in turn have [[lambda calculus]] as their even more abstract, mathematical, foundation),

* lists that are [[First class object|first class]] (including ''lists of lists/arrays''),

* ''First class'' sprites (in other words [[Prototype-based programming|prototype-oriented instance-based classless object programming]]),
