Javascript 如何对数组的对象进行分组和分离

如何对来自服务器的数组对象进行分组和分离。像这样的数组： （MOVINGSTATE

s

这意味着停止和

m

移动。XPOINT和YPOINT这意味着汽车的纬度和经度。）

我想知道如果一些

MOVINGSTATE

连续

s

转到新数组，当

MOVINGSTATE

更改为

m

转到新数组，然后再次

MOVINGSTATE

更改为

s

转到新数组。所有这些新数组都是另一个主数组的对象。 我用

但输出如下：

{m:Array(2),s:Array(3)}

我想要这样的超能力：

[
 [
  {MOVINGSTATE: "s",XPOINT:53.9172866,YPOINT: 26.518275},
  {MOVINGSTATE: "s",XPOINT: 53.9172866,YPOINT: 26.518275}
  ],
 [
  {MOVINGSTATE: "m",XPOINT: 54.0215383,YPOINT: 26.5275599},
  {MOVINGSTATE: "m",XPOINT: 54.0102666,YPOINT: 26.4989583}
 ],
 [
  {MOVINGSTATE: "s",XPOINT: 54.0016599,YPOINT: 26.5478316}
 ]
]

如何感谢您的帮助尝试以下方法：

let arr = 
[{MOVINGSTATE: "s",XPOINT:53.9172866,YPOINT: 26.518275},
{MOVINGSTATE: "s",XPOINT: 53.9172866,YPOINT: 26.518275},
{MOVINGSTATE: "m",XPOINT: 54.0215383,YPOINT: 26.5275599},
{MOVINGSTATE: "m",XPOINT: 54.0102666,YPOINT: 26.4989583},
{MOVINGSTATE: "s",XPOINT: 54.0016599,YPOINT: 26.5478316}];

  let result =  arr.reduce( (accumulator, cur) => {
    const key = cur["MOVINGSTATE"];
    const keyExists = accumulator.find(obj => obj.key === key);
    if (!keyExists) {
      accumulator.push({key,value:[cur]});
      return accumulator;      
    } else if(accumulator[accumulator.length -1] && accumulator[accumulator.length -1].key === key){
        accumulator[accumulator.length -1].value.push(cur);
        return accumulator;
    } else {
      accumulator.push({key,value:[cur]});
      return accumulator; 
    }
        
  }, [])
  .map(obj => obj.value)
