• pattern matching #121

New Feature

• added intersection combinator fix #111

  Example

  const Min = t.subtype(t.String, function (s) { return s.length > 2; }, 'Min');
  const Max = t.subtype(t.String, function (s) { return s.length < 5; }, 'Max');
  const MinMax = t.intersection([Min, Max], 'MinMax');
  
  MinMax.is('abc'); // => true
  MinMax.is('a'); // => false
  MinMax.is('abcde'); // => false
  

Internal

• optimised the generation of default names for types

• added aliases for pre-defined irreducible types fix #112
• added overridable stringify function to handle error messages and improve performances in development (replaces the experimental options.verbose)

• added options.verbose (default true) to handle messages (set options.verbose = false to improve performances in development)

• add support to types defined as ES6 classes #99
• optimized for production code: asserts and freeze only in development mode
• add is(x, type) function
• add isType(x) function
• add stringify(x) function

• numeric types on enums #93 (thanks @m0x72)
• remove asserts when process.env.NODE_ENV === 'production' #100
• do not freeze if process.env.NODE_ENV === 'production' #103
• func without currying #96 (thanks @tmcw)
• remove useless exports #104
• drop bower support #101
• remove useless exports
  • Type
  • slice
  • shallowCopy
