Jack

Jack is a new language designed by Tim Caswell with the explicit goal of being easy to explain the semantics while still being powerful.

Jack is a scripting language aimed at kids learning to program as well as professionals who yearn for a simpler language (like me).

Language Features

• Immutable unicode strings
• Mutable Binary buffers (fixed length)
• Booleans
• Null
• Integers
• Floating Point Numbers
• First class and higher-order functions.
  • Lexical closure.
• Basic key/value maps for objects (no inheritance or prototype chain)
• Dense Arrays
• Everything is an expression where possible.
• Implicit return values
• Unified looping syntax that works on objects, arrays, and generator functions
• Object metamethods for advanced usage (get, set, keys, length, call)
  • Allows objects to act like functions, arrays, etc.

My guiding principle while adding language features and semantics is:

Keep it Simple, Keep it Safe
