console.log(holiday_result);I'm trying to .slice(0,10) the date. I get it displayed like this "2022-05-16T22:00:00.000Z", but I need it as "2022-05-16", so I try to date.slice(0, 10) it's not working though.
You can first map over result_database using Array.prototype.map and update the date property and then filter the array based on holiday_date using Array.prototype.filter.
const
result_database = [
{ id: 1, name: "Tom Riddle", date: "2022-05-16T22:00:00.000Z" },
{ id: 2, name: "Hank Some", date: "2022-05-19T22:00:00.000Z" },
{ id: 3, name: "Family Man", date: "2022-05-17T22:00:00.000Z" },
],
holiday_date = new Date().toJSON().slice(0, 10),
holiday_date_remove = result_database
.map((item) => ({ ...item, date: item.date.slice(0, 10) }))
.filter(({ date }) => date !== holiday_date);
console.log(holiday_date_remove);You should split by "T" when it's in ISOString format.
const yourTypeDate = new Date().toISOString().split('T')[0];
This comparing below is working, it will check if the db date is equal today date, if it's will remove the index, the filter is working.
result_database = [
{ id: 1, name: "Tom Riddle", date: "2022-05-16T22:00:00.000Z" },
{ id: 2, name: "Hank Some", date: "2022-05-19T22:00:00.000Z" },
{ id: 3, name: "Family Man", date: "2022-05-17T22:00:00.000Z" },
];
var holiday_date = new Date().toISOString().split('T')[0];
let holiday_date_remove = result_database.filter(
(item1) =>
!result_database.find(
(item2) => {
item2.date = item2.date.split('T')[0];
return ((item1.name == item2.name) && (item2.date.split('T')[0] == holiday_date));
}
)
);
const holiday_result = [
...new Map(
holiday_date_remove.map((item) => [JSON.stringify(item.name), item])
).values(),
];
console.log(holiday_result);
