I have this array. How do I use underscore '_.sortBy' to sort it according to start date?
[ { id: 'oljw832021kjnb389xzll323jk', start: { dateTime: '2013-09-26T13:30:00-07:00' }, end: { dateTime: '2013-09-26T14:30:00-07:00' }, }, { id: 'ed7l5tmckdp0lm90nvr4is3d4c', start: { dateTime: '2013-09-26T15:30:00-07:00' }, end: { dateTime: '2013-09-26T16:30:00-07:00' }, }, { id: 'etmasdsackdp0kjl0nvrkopioqw', start: { dateTime: '2013-09-26T18:00:00-07:00' }, end: { dateTime: '2013-09-26T19:00:00-07:00' }, } ]

sortBy() function is used to sort all the elements of the list in ascending order according to the function given to it as a parameter. Passing the array with a function which returns the number and it will sort the array in ascending order and return an array. The array can be both of numeric values and string values.
To sort an array of objects, you use the sort() method and provide a comparison function that determines the order of objects.
Use an iterator function, not a single string for a property:
_.sortBy(arr, function(o) { return o.start.dateTime; }) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
