Latest Version

  }
}

Usage

var Glasses = require('glasses');
var arr = [1, 2, 3]
console.log(Glasses.methods(arr));

gives you a list of all the methods on an array:

[ 'unshift',
  'pop',
  'indexOf',
  'every',
  'slice',
  'reduce',
  'forEach',
  'reverse',
  'shift',
  'splice',
  'lastIndexOf',
  'concat',
  'toString',
  'push',
  'constructor',
  'map',
  'join',
  'sort',
  'filter',
  'some',
  'reduceRight',
  'toLocaleString',
  '__defineSetter__',
  '__defineGetter__',
  'propertyIsEnumerable',
  'valueOf',
  'isPrototypeOf',
  'hasOwnProperty',
  '__lookupSetter__',
  '__lookupGetter__' ]

Passing a second argument of true restricts the lookup to just the object and its immediate prototype:

console.log(Glasses.methods(arr, true));

results in

[ 'unshift',
  'pop',
  'indexOf',
  'every',
  'slice',
  'reduce',
  'forEach',
  'reverse',
  'shift',
  'splice',
  'lastIndexOf',
  'concat',
  'toString',
  'push',
  'constructor',
  'map',
  'join',
  'sort',
  'filter',
  'some',
  'reduceRight',
  'toLocaleString' 
]

Glasses(blah) is a superset of the methods call that includes non-function properties. For example with an array, the result would also include "length". There's also Glasses.attributes for just non-function properties.
