Building a Prototype
SynopsisPrototype("Proto", {
methods: {
one: function () { return 1 }
}
})Prototype(name, properties)The global Prototype-function is Joose's facility for prototype-based object-oriented programming. It supports the same features as the Class-builder with one important difference: All instances of the prototype get their own meta-object. That means, when you manipulate an instance of a prototype using the meta interface, these changes will only effect that very instance. When you instantiate the manipulated prototype var proto2 = new proto1.constructor() , the new prototype-instance will receive all the changes, though. The creation of the instance-meta-object is done lazily, so you only pay a performance price when you actually do meta programming. |
