To streamline the array, only elements with a value equal to or greater than the set threshold will be retained. These selected elements will then be used to create a new array comprising multiple objects. Each object will consist of two properties: the start and end timestamps.
If consecutive elements have timestamps that are 10 minutes apart, they will be grouped together within the same object. The start timestamp will be that of the first element, while the end timestamp will be the timestamp of the last element in the group plus 10 minutes.
In cases where there are no consecutive elements, the start timestamp will remain as it is, and the end timestamp will be the start timestamp plus 10 minutes.
const data = [{
timestamp: '2021-11-23T14:00:00+0000',
amount: 21
},
{
timestamp: '2021-11-23T14:10:00+0000',
amount: 27
},
{
timestamp: '2021-11-23T14:20:00+0000',
amount: 31
},
{
timestamp: '2021-11-23T14:30:00+0000',
amount: 29
},
{
timestamp: '2021-11-23T14:40:00+0000',
amount: 18
},
{
timestamp: '2021-11-23T14:50:00+0000',
amount: 17
},
{
timestamp: '2021-11-23T15:00:00+0000',
amount: 25
},
{
timestamp: '2021-11-23T15:10:00+0000',
amount: 21
}
]
const threshold = 25
const aboveThreshold = data.filter(element => element.amount >= threshold)
const workSchedule = []
for (let i = 0; i < aboveThreshold.length; i++) {
if (i === 0) {
workSchedule.push({
start: aboveThreshold[i].timestamp,
end: aboveThreshold[i + 1].timestamp
})
}
if (i > 0 && i < aboveThreshold.length - 1) {
if (aboveThreshold[i].timestamp.slice(11, 13) === aboveThreshold[i + 1].timestamp.slice(11, 13)) {
workSchedule.push({
start: aboveThreshold[i].timestamp,
end: aboveThreshold[i + 1].timestamp
})
}
}
if (i === aboveThreshold.length - 1) {
workSchedule.push({
start: aboveThreshold[i].timestamp,
end: aboveThreshold[i].timestamp
})
}
}
console.log(workSchedule)Ultimately, the desired result would look like this:
[
{
start: '2021-11-23T14:10:00+0000',
end: '2021-11-23T14:40:00+0000'
},
{
start: '2021-11-23T15:00:00+0000',
end: '2021-11-23T15:10:00+0000'
}
]
I hope this explanation clarifies the process 😬 Is there a more straightforward approach to achieve this outcome?
