微信小程序如何单独取出动态数组中的所有highPressureValue值放入新数组中

使用filter后是没有单独取出来，条件不会写，

选择需要的项用filter，数据项转换成其他结构用map

PresureList=[{highPressureValue:1,createTime:null},{highPressureValue:2,createTime:null},{highPressureValue:3,createTime:null}];
highPressureList=PresureList.map(v=>v.highPressureValue);//[1, 2, 3]
//需要对象
//highPressureList=PresureList.map(v=>{return {highPressureValue:v.highPressureValue}});//[{"highPressureValue":1},{"highPressureValue":2},{"highPressureValue":3}]
