排序之后的model如何再转回成Object对象？

aboutToAppear(): void { 
  let model: [string, Object][] = Object.entries(bean); 
  model.sort((a, b) => { 
  return a[0].localeCompare(b[0]); 
}); 
let res: Record<string, Object> = {}; 
model.forEach((value, key) => { 
  if (key != undefined && key != null) { 
    res[value[0]] = value[1]; 
  } 
}) 
console.log(JSON.stringify(res)) 
}
