I have an array like this :
array = [
{
"title": "a",
"date": "2021-10-25T18:00:00.000"
},
{
"title": "b",
"date": "2021-10-20T18:00:00.000"
},
{
"title": "b",
"date": "2021-10-28T18:00:00.000"
},
{
"title": "b",
"date": "2021-10-30T18:00:00.000"
},
{
"title": "b",
"date": "2021-10-26T18:00:00.000"
}
]
And I want to sort it with the nearest object from today first. I try with sort but I think, I don't have the good method to do this.
This is what I tried :
array.sort((a, b) => {
return (new Date(b.battle_start) > new Date()) - (new Date(a.battle_start) < new Date())
})
And this is what I want
array = [
{
"title": "b",
"date": "2021-10-26T18:00:00.000"
},
{
"title": "a",
"date": "2021-10-25T18:00:00.000"
},
{
"title": "b",
"date": "2021-10-28T18:00:00.000"
},
{
"title": "b",
"date": "2021-10-30T18:00:00.000"
},
{
"title": "b",
"date": "2021-10-20T18:00:00.000"
}
]
Your code can be adapted to use Math.abs, so that distance to past or future will be regarded in the same way:
const array = [{"title": "a","date": "2021-10-25T18:00:00.000"},{"title": "b","date": "2021-10-20T18:00:00.000"},{"title": "b","date": "2021-10-28T18:00:00.000"},{"title": "b","date": "2021-10-30T18:00:00.000"},{"title": "b","date": "2021-10-26T18:00:00.000"}];
let now = Date.now();
array.sort((a,b) =>
Math.abs(Date.parse(a.date) - now) - Math.abs(Date.parse(b.date) - now)
);
console.log(array);You should be able to do that via :
array.sort((a, b) => {
return (Math.abs(new Date(a.battle_start) - new Date())) - Math.abs((new Date(b.battle_start) - new Date()))
})
What you want to compare is the distance between "now" and the target date.
