@ and @@

This module provides an Ruby style aliases for:

• this in the form of @
• this.constructor in the form of @@

Example

Animal = (type, color) {
  @type = type
  @color = color
  @@count += 1
  @@all.push @
}

@ in bang function calls

In the case of unwrapped async calls via the bang postfix, @ will actually refer to the outer this.

Since we can refer to both via this method, binding becomes unecessary.

Example

Class.cacheData = {
  d = $.get! "/" 
  @data = d      // outer this
  this.data = d  // inner this
  return @
}
