我想把这个数据数组过滤成州和市array.如何使用lodash或其他更好的方法实现这一点，而不是使用循环和维护额外的array.
data: [
{ id: 1, name: Mike, city: philps, state: New York},
{ id: 2, name: Steve, city: Square, state: Chicago},
{ id: 3, name: Jhon, city: market, state: New York},
{ id: 4, name: philps, city: booket, state: Texas},
{ id: 5, name: smith, city: brookfield, state: Florida},
{ id: 6, name: Broom, city: old street, state: Florida},
]
哪个用户单击state，就会出现状态列表.
{state: New York, count: 2},
{state: Texas, count: 1},
{state: Florida, count: 2},
{state: Chicago, count: 1},
当用户单击特定状态时，将显示该状态的cities个列表.例如，当用户点击纽约州，
{id:1, name: Mike, city: philps}
{id:3, name: Jhon, city: market}
