i have an object like this:
0: {start: '2022-02-23T09:30:00', end: '2022-02-23T10:00:00',…}
1: {start: '2022-02-23T10:00:00', end: '2022-02-23T10:30:00',…}
2: {start: '2022-02-23T10:30:00', end: '2022-02-23T11:00:00',…}
3: {start: '2022-02-23T11:00:00', end: '2022-02-23T11:30:00',…}
4: {start: '2022-02-23T12:00:00', end: '2022-02-23T12:30:00',…}
5: {start: '2022-02-23T13:00:00', end: '2022-02-23T13:30:00',…}
6: {start: '2022-02-23T13:30:00', end: '2022-02-23T14:00:00',…}
7: {start: '2022-02-23T14:00:00', end: '2022-02-23T14:30:00',…}
8: {start: '2022-02-23T14:30:00', end: '2022-02-23T15:00:00',…}
9: {start: '2022-02-23T15:00:00', end: '2022-02-23T15:30:00',…}
10: {start: '2022-02-23T15:30:00', end: '2022-02-23T16:00:00',…}
11: {start: '2022-02-23T16:00:00', end: '2022-02-23T16:30:00',…}
12: {start: '2022-02-23T16:30:00', end: '2022-02-23T17:00:00',…}
what i'm trying to do is getting the first element that has a free time in between those start and end
For example, if we look at the third element it starts at 11:00 and ends at 11:30 and the previous elements are contiguos. The 4th element instead starts at 12:00 so from 11:30 and 12:00 there are 30 minutes free. So what i need to do is get the end (or the entire element) property of the first element that has a next element that doesn't have a contiguos start
update: i tried something like this
const latestAppointment = [...appointments].sort((a, b) => (new Date(a.end)) < (new Date(b.end)) ? -1 : 1)
i hope i explained myself Thank you
Looking for something like this?
myArray.filter((e, i, o) => e.end !== o[i+1]?.start)?.shift();
const times = {
0: {
start: '2022-02-23T09:30:00',
end: '2022-02-23T10:00:00'
},
1: {
start: '2022-02-23T10:00:00',
end: '2022-02-23T10:30:00'
},
2: {
start: '2022-02-23T10:30:00',
end: '2022-02-23T11:00:00'
},
3: {
start: '2022-02-23T11:00:00',
end: '2022-02-23T11:30:00'
},
4: {
start: '2022-02-23T12:00:00',
end: '2022-02-23T12:30:00'
},

}
const res = Object.values(times).filter((e, i, o) => e.end !== o[i+1]?.start)?.shift();
console.log(res);
