按自定义逻辑对 object 键进行排序

Question

I have an object in javascript that looks like this:

const inventory = {
   fall: { 'Category 1': [], 'Category 2': [] },
   spring: { 'Category 1': [], 'Category 3': [] },
   winter: { 'Category 3': [], 'Category 4': [] },
   summer: { 'Category 4': [], 'Category 5': [] }
}

How can I sort by keys so that those are ordered as follows:

1. spring
2. summer
3. fall
4. winter

Answer 1

Destructuring assignment

const { spring, summer, fall, winter } = {
  fall: { 'Category 1': [], 'Category 2': [] },
  spring: { 'Category 1': [], 'Category 3': [] },
  winter: { 'Category 3': [], 'Category 4': [] },
  summer: { 'Category 4': [], 'Category 5': [] }
};

const inventory = { spring, summer, fall, winter }

Answer 2

You just need to create new object with this sorting.

 const inventory = { fall: { 'Category 1': [], 'Category 2': [] }, spring: { 'Category 1': [], 'Category 3': [] }, winter: { 'Category 3': [], 'Category 4': [] }, summer: { 'Category 4': [], 'Category 5': [] } } const { fall, spring, winter, summer } = inventory; const sortingInventory = { spring, summer, fall, winter, } console.log(sortingInventory)

FOR SORTING ALGHPITICALLY .

 const inventory = { fall: { 'Category 1': [], 'Category 2': [] }, spring: { 'Category 1': [], 'Category 3': [] }, winter: { 'Category 3': [], 'Category 4': [] }, summer: { 'Category 4': [], 'Category 5': [] } } const result = Object.fromEntries(Object.entries(inventory).sort((a, b) => { return a[0].localeCompare(b[0]) })) console.log(result)
