for all the examples on the internet i cant figure out when and how is kotlins let ran?
if(phones.size == 0){
phones.add("")
}
return phones[0]
so if phones list size is 0, we add empty string and return that instead.
Now how would one do same with let ?
phones.let {
return ""
}
does this work with size 0, or do i have to have null list?
do i need return keyword, if yes, where?
is the above fun always going to return empty string? or just when phones is null?
when is this let code block even ran?
