How to sort LinkedHashMap by values in Kotlin?

Question

To sort by keys I can use

map.toSortedMap() 

But what is the best way to sort LinkedHashMap by values in Kotlin?

Answer 1

map.toList()     .sortedBy { (key, value) -> value }     .toMap() 

Answer 2

You can use sortedBy with destructuring syntax and leave the first argument blank:

map.toList().sortedBy { (_, value) -> value }.toMap() 

or you can do it without destructuring syntax (as mentioned by aksh1618 in the comments):

map.toList().sortedBy { it.second }.toMap() 

and if you want to iterate the result right away, you don't even need toMap():

map.toList()     .sortedBy { it.second }     .forEach { (key, value) -> /* ... */ }
