js gets the maximum and minimum value in an array (object)

let arr:array = []
// 取最大值：Math.max.apply(Math, arr.map(function(o) {return o.value}))
// 取最小值：Math.min.apply(Math, arr.map(function(o) {return o.value}))

var array=[
{ “index_id”: 111, “area_id”: “18335623”, “name”: “Satisfaction”, “value”: “100” }, { “index_id”: 112, “area_id”: “18335624” ", "name": "Satisfaction", "value": "20" }, { "index_id": 114, "area_id": "18335524", "name": "Satisfaction", "value": "10 ” }, { “index_id”: 113, “area_id”: “18335625”, “name”: “Satisfaction”, “value”: “80” } ];

Math.min.apply(Math, array.map(function(o) {return o.value}))

In this way, the maximum and minimum data are obtained
