forOwn

_.forOwn(object, [iteratee=_.identity])

迭代对象自身可枚举字符串键属性，并为每个属性调用 iteratee。迭代器使用三个参数调用：(value, key, object)。迭代函数可以通过显式返回 false 提前退出迭代。

¥Iterates over own enumerable string keyed properties of an object and invokes iteratee for each property. The iteratee is invoked with three arguments: (value, key, object). Iteratee functions may exit iteration early by explicitly returning false.

参数

¥Arguments

1. object (对象)：要迭代的对象。

   ¥object (Object): The object to iterate over.

2. [iteratee=_.identity] (函数)：每次迭代调用的函数。

   ¥[iteratee=_.identity] (Function): The function invoked per iteration.

返回

¥Returns

(对象)：返回 object。

¥(Object): Returns object.

示例

¥Example

function Foo() {
  this.a = 1;
  this.b = 2;
}

Foo.prototype.c = 3;

_.forOwn(new Foo, function(value, key) {
  console.log(key);
});
// => Logs 'a' then 'b' (iteration order is not guaranteed).
