Dates string array is constructed from backend data object as below:
const dates: string[] = this.data.map((item:any) => item.date.jsdate);
The result is
dates = [
Thu Jan 12 2015 00:00:00 GMT+0530 (India Time),
Tue Feb 25 2015 00:00:00 GMT+0530 (India Time),
Sun Jan 28 2016 00:00:00 GMT+0530 (India Time)
]
typeof(dates) is "object"
How to find the get the latest date among the jsdates array?
Is it possible to apply max function of date-fns?
I can offer one solution, using the momentjs ( https://momentjs.com/ ) library.
You can sort the dates using:
dates = dates.sort((a,b) => moment(a).diff(moment(b));
Then if you want the latest date you could take the last element from that array:
return dates[dates.length-1];
You should also be able to do this without moment:
dates = dates.sort((a,b) => new Date(b) - new Date(a));
Convert each to a Date
object and compare using getTime()
function.
var dates = [ 'Thu Jan 12 2015 00:00:00 GMT+0530 (India Time)', 'Tue Feb 25 2015 00:00:00 GMT+0530 (India Time)', 'Sun Jan 28 2016 00:00:00 GMT+0530 (India Time)' ] console.log( dates.sort((a,b)=>new Date(b).getTime() - new Date(a).getTime())[0] )
