Douglas Crockford has some very good explanations of inheritance in JavaScript:
Douglas Crockford 对 JavaScript 中的继承有一些很好的解释：
- prototypal inheritance: the 'natural' way to do things in JavaScript
- classical inheritance: closer to what you find in most OO languages, but kind of runs against the grain of JavaScript

extend = function(destination, source) {
for (var property in source) {
destination[property] = source[property];
}
return destination;
};
You could also add filters into the for loop.
您还可以将过滤器添加到 for 循环中。
