X:style

XTK coding style draft

Table of Contents Class Design Class variables / Properties Local variables Loops

Class Design

• if possible, always inherit from X.base - this enables the event system
• each class has a className attribute (for duck typing and down casting)

  /**
   * @inheritDoc
   * @const
   */
  this['className'] = 'renderer';

• export symbols (only methods/functions) to avoid optimization by the compiler but only as little as required since it blows up the library size

Class variables / Properties

• Only public or protected properties
• Public properties replace simple getters like this (which avoids optimization by the compiler):

 this['container'] = _container;

• Protected properties (will be renamed during optimization)

 this.objects = new X.array();

Local variables

• always start with a underscore (_)

Loops

• decrementing while loop is faster than for
• Fast Duff's Device is the fastest but takes more lines of code
