hey, how can I trim last 4 or 5 characters from string using collection functions?

[diesieben07]

What exactly do you mean by "collection functions"? If you want to remove the last 4 characters of a String, substring is what you want:

val s = "Hello World"
s.substring(0, s.length - 5)

You can use `dropLast`: "Hello World!".dropLast(5)

also maybe it’s a good question for #getting-started
