isEqualWith

_.isEqualWith(value, other, [customizer])

此方法与 _.isEqual 类似，不同之处在于它接受 customizer，调用该方法可比较值。如果 customizer 返回 undefined，则比较将由该方法处理。customizer 使用最多六个参数来调用：(objValue, othValue [, index|key, object, other, stack])。

¥This method is like _.isEqual except that it accepts customizer which is invoked to compare values. If customizer returns undefined, comparisons are handled by the method instead. The customizer is invoked with up to six arguments: (objValue, othValue [, index|key, object, other, stack]).
