Matching two dates - TypeScript

Question

I have problems with task which looks like pretty simply. I need to match two variables and return true if match and false if not.

I have made method which check it

    isAnyApplicationFromToday(): boolean {
      this.userApplications.forEach(application => {
        if (application.registerDate.toString() == this.today.toString()) {
          return true;
        }
      });
    return false;
  }

but it always return false.

Funny is that, if I console.log(), variable values match.

I tried already combination:

if (application.registerDate.toString() === this.today.toString())
if (application.registerDate === this.today)
if (application.registerDate == this.today)

any ideas ?

EDIT:

  isAnyApplicationFromToday(): boolean {
    let isAny = false;
      this.userApplications.forEach(application => {
        if (application.registerDate.toString() === this.today.toString()) {
          isAny = true;
        }
      });
    return isAny;
  }

work just fine.

I suggest you to use timestamp. Convert date into timestamp and then compare. — Sachin Shah, Dec 08 '18 at 12:29
The problem is you are returning inside the `forEach`, instead of the main function Take a look here: https://stackoverflow.com/questions/34653612/what-does-return-keyword-mean-inside-foreach-function — rpadovani, Dec 08 '18 at 12:34
The `forEach` takes in a function. You're example is taking a function that returns true. This has no effect on the outer function. What you intend is for the outer function `isAnyApplicationFromToday` to return the result of the innerfunction. I suggest you do something like this: isAnyApplicationFromToday(): boolean { var result = false; this.userApplications.forEach(application => { result = application.registerDate.toString() == this.today.toString(); }); return result; } — Rafiek, Dec 08 '18 at 12:37
