请各位大佬指点！数组的归纳合并十分感谢

Question

letkindList=[
{kind:"高值",useMoney:"1500",num:"1"},
{kind:"低值",useMoney:"200",num:"2"},
{kind:"高值",useMoney:"1000",num:"1"},
{kind:"中值",useMoney:"800",num:"2"},
{kind:"中值",useMoney:"300",num:"10"}
];
//希望的到目标数组，相同类的数量总和和金额总和
[
{kind:"高值",useMoney:"2500",num:"2"},
{kind:"低值",useMoney:"200",num:"2"},
{kind:"中值",useMoney:"1100",num:"12"}
]
