I want o find overlapped time slot with small code. Lets there are time slots:
const slots = [
{
start_time: '10:30',
end_time: '11:00'
},
{
start_time: '11:30',
end_time: '12:00'
}
]
And I got the value from user as:
const inputStartTime = '10:50';
const inputEndTime = '11:20';
I think, there will be no overlapping if inputStartTime > slots.end_time and inputEndTime < slots.start_time. So, I want to set a variable such as const overlappedSlots = // and get the output of that variable as (console.log(overlappedSlots)):
[{
start_time: "10:30",
end_time: "11:00"
}]
But, I can't get this output by writing this function:
const inputStartTime = '10:50';
const inputEndTime = '11:20';
const slots = [
{
start_time: '10:30',
end_time: '11:00'
},
{
start_time: '11:30',
end_time: '12:00'
}
]
const overlappedSlots = slots.filter(slot => !slot.end_time < inputStartTime || !slot.start_time > inputEndTime);
console.log(overlappedSlots)What I was doing wrong there?
The error is when you use ! without parenthesis
const inputStartTime = '10:50';
const inputEndTime = '11:20';
const slots = [{
start_time: '10:30',
end_time: '11:00',
},
{
start_time: '11:30',
end_time: '12:00',
},
];
const overlappedSlots = slots.filter(
(slot) => inputStartTime > slot.start_time || !(slot.start_time > inputEndTime));
console.log(overlappedSlots);the problem with your code remains with !
Try this :
const overlappedSlots = slots.filter(slot => !(slot.end_time < inputStartTime) || !(slot.start_time > inputEndTime));
console.log("over"+overlappedSlots);
use && instead of ||
this will give you the result you want
time start : 10:30 end time: 11:00
