I want to sort "ONAIR", "READY", "CLOSING", "CLOSED" order in JavaScript. Is it possible string value of Object's key in map or sort of JavaScript?
as is :
const list = [
{status: 'READY'},
{status: 'CLOSED'},
{status: 'ONAIR'},
{status: 'CLOSING'},
];
to be:
const list = [
{status: 'ONAIR'},
{status: 'READY'},
{status: 'CLOSING'},
{status: 'CLOSED'},
];
If I understand what you mean correctly. Try this:
const sortSequencely = ["ONAIR", "READY", "CLOSING", "CLOSED"];
const list = [
{status: 'READY'},
{status: 'CLOSED'},
{status: 'ONAIR'},
{status: 'CLOSING'},
];
console.log('Original list', list);
const listSorted = list.sort((a,b) => {
const indexA = sortSequencely.findIndex(x=>x === a.status);
const indexB = sortSequencely.findIndex(x=>x === b.status);
return indexA - indexB;
})
console.log('Sorted list', listSorted)One way to achieve this is with a dictionary which specifies the order you desire; then you can sort based on looking up the status values in that dictionary:
const list = [
{status: 'READY'},
{status: 'CLOSED'},
{status: 'ONAIR'},
{status: 'CLOSING'},
];
const order = { 'ONAIR' : 0, 'READY' : 1, 'CLOSING' : 2, 'CLOSED' : 3 }
list.sort((a, b) => order[a.status] - order[b.status]);
console.log(list)
