javascript - 在javascript中更改对象数组顺序的最佳方法是什么

Question

重新排序对象数组的最简单方法是什么？

我想根据组值重新排序(自定义顺序)

[ { groupValue: 'Corp',
    doclist: { numFound: 259, start: 0, maxScore: 1.1320078, docs: [Object] } },
  { groupValue: 'Phone',
    doclist: { numFound: 7975, start: 0, maxScore: 1.2560269, docs: [Object] } },
  { groupValue: 'Shop',
    doclist: { numFound: 9, start: 0, maxScore: 1.2556685, docs: [Object] } } ]

如果我传入带有组值的参数，则对应于组值的特定对象应该出现在顶部

有点像

function ("Shop",originalArray){
 return newArray;
}

应该返回:

    [ { groupValue: 'Shop',
        doclist: { numFound: 9, start: 0, maxScore: 1.2556685, docs: [Object] } },
{ groupValue: 'Corp',
        doclist: { numFound: 259, start: 0, maxScore: 1.1320078, docs: [Object] } },
      { groupValue: 'Phone',
        doclist: { numFound: 7975, start: 0, maxScore: 1.2560269, docs: [Object] } }]

这应该可以工作，给出一个新数组并且应该只遍历一次原始数组。

var data = [{
  groupValue: 'Corp',
  doclist: {
    numFound: 259,
    start: 0,
    maxScore: 1.1320078,
    docs: [Object]
  }
}, {
  groupValue: 'Phone',
  doclist: {
    numFound: 7975,
    start: 0,
    maxScore: 1.2560269,
    docs: [Object]
  }
}, {
  groupValue: 'Shop',
  doclist: {
    numFound: 9,
    start: 0,
    maxScore: 1.2556685,
    docs: [Object]
  }
}];

function goFirst(d, daFirst) {
  var r = [];

  d.forEach((e) => {
    if (e['groupValue'] === daFirst)
      r.unshift(e);
    else
      r.push(e);
  })

  return r;
}

console.log(goFirst(data, 'Shop'));
