set

Generic Set container

Installation

$ component install component/set

Example

var Set = require('set');
var set = new Set;

set.add('foo');
set.add('foo');
set.add({ some: 'object' });
set.remove('foo');

set.values();
// => [{ some: 'object' }]

Equality

Set supports an .equals(other) method when present, for example you may then add two separate User instances that are identified as being the same via their name:

User.prototype.equals = function(user){
  return this.name == user.name;
};
