Meteor error explanation

error.js

// see http://docs.meteor.com/#/full/meteor_error

var error = new Meteor.Error('error-name', 'reason');
alert(error) //=> Error: reason [error-name]
alert(error.reason) //=> reason
alert(error.error) //=> error-name

// Explanation.. alert(error) is the same as going alert(error.toString()), which results in "Error: error.reason [error.error]"
