How to get max element of array and its corresponding index

How can we get the max element of the array with its corresponding index?

Ex : “somefield” : [1,2,2,2,2,1,1,1,1]

Max element is 2 and indexes are 1,2,3,4

Hey @vaidyarm,

Use the following expression in a mapper to get the expected result:

$array.map((x,index)=>{"value":x,"index":index}).filter(x=>x.value==($array.sort((a,b)=>b-a)[0]))

This will produce an array of objects, which will contain the max value, and It’s corresponding index.

Hey, did the similar, but keeping the filter in one mapper and sort as snap.

Thanks for input!!
