Why replace char doesn't work for Kotlin while calling regular replace on char function [duplicate]

Question

I am calling replace() on a string to change the chars but for some reason it does not change it.

 var result = "Hi!"
 result.replace('i','z')

In logs I still see Hi!

Strings are immutable. When you call replace, the function returns a new String instance. You'll have to assign the result to something if you want to use it elsewhere.

var result = "Hi!"
result = result.replace('i','z')
