I have an array of objects in javascript where I have employees login timings. I want to find if an employee has worked more then 5 hours consecutively then he/she will get a break. Otherwise if an employee worked more than 5 hours, but not consecutively, then they do not get a break.
Here is the code - it currently is just checking the number of hours an employee has worked, but it is not checking for consecutive hours.
checkBreakTimings() {
let breakTimes = "";
const timings = [
{
timeIn: '11:00',
timeOut: '12:00',
},
{
timeIn: '12:00',
timeOut: '13:00',
},
{
timeIn: '14:00',
timeOut: '16:00',
},
{
timeIn: '16:00',
timeOut: '18:00',
}
];
let h = 0;
timings.forEach(e => {
const ms = moment(e.timeOut, "HH:mm").diff(moment(e.timeIn, "HH:mm"));
h = h + = Number(moment.duration(ms).asHours());
});
if(h > 5 )
{
breakTimes = "Yes";
}
}
return breakTimes;
}
As you can see from the above timings that an employee worked 8 hours out for which 6 hours are consecutive from 14:00 to 18:00 here break will be applied, but the above 2 timings are not consecutively more than 5 hours.
My problem is - is there any way to find out the number of consecutive hours from an array using JavaScript or in moment.js
Try like following snippet:
const checkBreakTimings = () => {
let breakTimes = "";
const timings = [
{timeIn: '11:15', timeOut: '12:00', },
{timeIn: '12:00', timeOut: '13:00', },
{timeIn: '13:00', timeOut: '15:46', },
{timeIn: '16:00', timeOut: '18:00', }
];
let h = 0;
let consecutive = 0
let lastOut = null
timings.forEach(e => {
const ms = moment(e.timeOut, "HH:mm").diff(moment(e.timeIn, "HH:mm"));
let worked = Number(moment.duration(ms).asHours())
consecutive = worked
if (lastOut === e.timeIn) { //👈 compare if timeIn is equal to last timeOut and sum values
consecutive += worked
} else consecutive = 0
lastOut = e.timeOut
if (consecutive > 5) breakTimes = "Yes" //👈 it's more then 5 hours
h = h + Number(moment.duration(ms).asHours());
});
console.log(breakTimes);
}
