How to filter items by day?

Question

JavaScript

You need to filter by an array with objects for a week, day, month.
The object stores a specific day.

Data format:

"test": [
    {
      "id": "uVB6FJQUH",
      "type": "kino",
      "total": 70,
      "date": "17.01.2021",

    }]

I did filtering by day, I can’t figure out how to do it in a week, as far as I understand, you first need to create an interval of days for the WEEK button (Calendar week) and compare whether my object is included in it, tell me how to implement it, I’m doing it on the front.

Answer 1

you can use the date-fns library . Namely, the methods:

• subBusinessDays
  
• isWithinInterval
  

Implementation

const lastBusinessWeekStart = subBusinessDays(new Date(), 7);
const lastBusinessMonthStart = subBusinessDays(new Date(), 30);
// фильтр неделя:
test.filter(({ date }) => isWithinInterval(
  new Date(date),
  { start: lastBusinessWeekStart, end: new Date() }
));

//фильтр месяц:
test.filter(({ date }) => isWithinInterval(
  new Date(date),
  { start: lastBusinessMonthStart, end: new Date() }
));
