# 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
