00:00:09,240 --> 00:00:14,580
Hi there, I hope you were able to finish this challenge that should be pretty easy.

2
00:00:14,730 --> 00:00:21,210
And in this video, I'm going to share with you the solution or actually one of the solutions, because

3
00:00:21,210 --> 00:00:24,690
there's never just one way of solving problems.

4
00:00:24,930 --> 00:00:27,420
So I'm just going to share with you my solution.

5
00:00:27,570 --> 00:00:35,640
And if you did it differently, we would love to see how you solved it so you can just share your solution

6
00:00:35,640 --> 00:00:37,020
in the Q&A section.

7
00:00:37,260 --> 00:00:44,820
OK, so going back to visuals to record, I just left these dates here, so I'm going to create two

8
00:00:44,820 --> 00:00:46,040
new variables.

9
00:00:46,050 --> 00:00:49,620
So the first one is going to be order date.

10
00:00:51,820 --> 00:01:00,550
Then we are going to create a new date object, and we know that we can pass either numeric arguments

11
00:01:00,550 --> 00:01:08,830
or string arguments if we just want to inform your month and date with pre numeric arguments.

12
00:01:08,860 --> 00:01:14,690
This is going to work so we can just do twenty, twenty then the month.

13
00:01:15,190 --> 00:01:20,550
Don't forget that March is not three because months they start from zero.

14
00:01:20,560 --> 00:01:22,900
So March is actually two.

15
00:01:24,250 --> 00:01:32,440
And the day is twenty six, if you want, you can do it like this, if you get confused with month starting

16
00:01:32,440 --> 00:01:36,510
from zero, you can just use the string argument.

17
00:01:36,790 --> 00:01:43,320
So then you can just type it like twenty, twenty three, twenty six.

18
00:01:43,330 --> 00:01:45,130
This is going to work as well.

19
00:01:45,340 --> 00:01:54,040
So now we have this date and we want to get the number of milliseconds since the apoc so we can calculate

20
00:01:54,040 --> 00:01:56,180
the interval between the two dates.

21
00:01:56,500 --> 00:02:03,550
So for this we are just going to use the get time method so that get time.

22
00:02:05,110 --> 00:02:11,860
Then we are just going to do the same thing for the delivery date.

23
00:02:13,870 --> 00:02:17,140
Which was April 2nd, so.

24
00:02:18,400 --> 00:02:19,030
April.

25
00:02:21,340 --> 00:02:28,240
Second, and now before we move ahead, let's just do consolidate that log, as we always do, and let's

26
00:02:28,240 --> 00:02:31,150
just try to send delivery date.

27
00:02:32,240 --> 00:02:34,280
Minus ordinate.

28
00:02:42,320 --> 00:02:48,890
So if we do this and refresh the page, as you can see, we're getting some number here and what is

29
00:02:48,890 --> 00:02:49,260
this?

30
00:02:49,460 --> 00:02:52,940
This is actually the difference in milliseconds.

31
00:02:53,180 --> 00:02:57,950
So this date has a number of milliseconds since the Abuk.

32
00:02:58,340 --> 00:03:04,680
This date has less milliseconds because it was prior to this second date.

33
00:03:04,970 --> 00:03:08,740
So between these two, we have a number of milliseconds.

34
00:03:09,110 --> 00:03:12,800
So how do we use it to calculate the dates?

35
00:03:14,650 --> 00:03:23,620
So we know that in one day, so let's go up to this table in one day, we have this amount of milliseconds.

36
00:03:24,100 --> 00:03:25,750
So if we do this.

37
00:03:26,720 --> 00:03:34,080
We can see that this product took seven days to be delivered, so this was actually pretty simple.

38
00:03:34,190 --> 00:03:42,200
But I want to share with you an even more simple solution because we don't need to use the get time.

39
00:03:42,470 --> 00:03:49,700
So let's not use the get time and let's just use the full object.

40
00:03:50,760 --> 00:03:52,710
To do a subtraction.

41
00:03:53,610 --> 00:03:57,840
So let's save this and let's refresh the page and see what happens.

42
00:03:58,050 --> 00:04:07,020
So, as you can see, JavaScript, just let us subtract that so we just subtract the delivery date from

43
00:04:07,020 --> 00:04:08,250
the order date.

44
00:04:08,250 --> 00:04:14,010
And JavaScript is just returning the same thing, which is the number of milliseconds between these

45
00:04:14,010 --> 00:04:14,460
dates.

46
00:04:14,680 --> 00:04:17,690
Then we just need to do what we did again.

47
00:04:18,000 --> 00:04:21,960
So I'm just going to get the number of milliseconds in one day.

48
00:04:23,680 --> 00:04:27,640
So I'm just going to create a new variable called lead time.

49
00:04:29,410 --> 00:04:38,380
Which is going to be this operation divided by the number of milliseconds in one day, so this time

50
00:04:38,380 --> 00:04:45,520
since we are not passing hours, we just have a round number, but we don't know if that's going to

51
00:04:45,520 --> 00:04:46,920
be the case every time.

52
00:04:46,930 --> 00:04:50,320
So it is better to just force.

53
00:04:53,970 --> 00:04:58,650
The round function, actually, not the round, but the floor function.

54
00:05:02,610 --> 00:05:04,290
So math that floor.

55
00:05:08,920 --> 00:05:14,110
And now, instead of sending it to the council, let's see what is the idea of that element.

56
00:05:18,270 --> 00:05:23,310
Let's select this, and this is the idea of the element delivery time.

57
00:05:23,610 --> 00:05:28,950
So again, document dot get Element by Bayada.

58
00:05:30,430 --> 00:05:35,050
This is the idea of that element, so in our TML.

59
00:05:37,130 --> 00:05:39,230
It's going to be the lead time.

60
00:05:40,760 --> 00:05:43,370
So saving this refreshing the page.

61
00:05:45,820 --> 00:05:51,770
And now we just solved this challenge, if you want to do an extra challenge, which would be cool.

62
00:05:51,790 --> 00:05:57,550
I'm not going to solve this one in video, but if you want to do it just to practice, you can do the

63
00:05:57,550 --> 00:05:58,180
opposite.

64
00:05:58,420 --> 00:06:04,200
So you can just get the order date and let's say you have the delivery time.

65
00:06:04,390 --> 00:06:12,880
So let's say your company takes, I don't know, 10 days to deliver the product, then try to calculate

66
00:06:13,120 --> 00:06:16,000
what is going to be the delivery date.

67
00:06:17,080 --> 00:06:20,800
So this is going to be very similar to what we just did.

68
00:06:21,670 --> 00:06:28,140
And it is going to be cool to practice a little more on working with date and time, so that was all.

69
00:06:28,150 --> 00:06:29,830
I hope you'll like this challenge.

70
00:06:29,830 --> 00:06:33,580
And in the next video, we are going to talk about time methods.

71
00:06:33,610 --> 00:06:34,360
I'll see you then.
