二维数组或数组对象多层嵌套（完全匹配）去重 如下：
let data = [4, 5, 6, 4, 3, 4, 5,
{
"discount": 10,
"maxBuyLimit": 10,
"minBuyLimit": 1,
"packageTicketPrice": [
"80.00",
"1520.00",
"1600.00"
],
"packageTicketUnitId": 17512319,
"setNumber": 1,
"ticketLevel": "H"
},
{
"discount": 5,
"maxBuyLimit": 5,
"minBuyLimit": 1,
"packageTicketPrice": [
"80.00",
"160.00",
"240.00"
],
"packageTicketUnitId": 17512334,
"setNumber": 2,
"ticketLevel": "H"
},
{
"discount": 10,
"maxBuyLimit": 10,
"minBuyLimit": 1,
"packageTicketPrice": [
"80.00",
"160.00",
"1600.00"

],
"packageTicketUnitId": 17512334,

},]
const noRepeat= (data) => {

console.log('去重--',noRepeat(data));
