Methods
与之相反_.mapValues
; 此方法创建一个具有与object
通过运行object
thru的每个自己的可枚举字符串键控属性生成的键值 相同的值的对象iteratee
。迭代器被调用三个参数:(value,key,object)。
3.8.0
object
(Object):迭代的对象。 [iteratee=_.identity]
(Function):每次迭代调用的函数。 (Object):返回新的映射对象。
_.mapKeys({ 'a': 1, 'b': 2 }, function(value, key) { return key + value; }); // => { 'a1': 1, 'b2': 2 }
