根据不同对象的等级对对象数组进行排序

let options = [{value: 'b', label: "test1"},{value: 'a', label: "test12"},{value: 'c', label: "test123"}];
let ranks = [{rank: 1, value: "a"},{rank: 2, value: "b"},{rank: 3, value: "c"}]; 

let temp = ranks.reduce((a,c) => Object.assign(a,{[c.value]:c.rank}), {});
options.sort((a,b) => temp[a.value] - temp[b.value]);
console.log(options);

var options = [
  {value: 'b', label: "test1"},
  {value: 'a', label: "test12"},
  {value: 'c', label: "test123"}
]


var ranks = [
  {rank: 1, value: "a"},
  {rank: 2, value: "b"},
  {rank: 3, value: "c"}
]

             
options.sort((a, b) => {
  return ranks.find(_ => _.value === a.value).rank - ranks.find(_ => _.value === b.value).rank
})

console.log (options)

var options = [{ value: 'b', label: "test1" }, { value: 'a', label: "test12" }, { value: 'c', label: "test123" }],
    ranks = [{ rank: 1, value: "a" }, { rank: 2, value: "b" }, { rank: 3, value: "c" }];
    
options.sort(
    (m => ({ value: a }, { value: b }) => m.get(a) - m.get(b))
    (ranks.reduce((m, { rank, value }) => m.set(value, rank), new Map))
);

console.log(options);
