How do I assign this modified array to a variable?

Question

Try to do this as a one-liner, a little confused why this doesn't work:

var= balh.getArrayOStrings('sdfsfd').each{ it.replaceAll("herp","derp") }

I call a method that returns an array of string. I loop over them and do a replace and assign back to var, but the modified strings in the array are not assigned back to var. Why not?

each returns the original list, try

balh = [:]
balh.getArrayOStrings = { x ->
    [ "sudhpa Herp", "pskaap herp", "herp lsjkda"]
}

var = balh.getArrayOStrings('sdfsfd').collect { it.replaceAll("herp","derp") }

=> [sudhpa Herp, pskaap derp, derp lsjkda]

Or just balh.getArrayOStrings('sdfsfd')*.replaceAll("herp","derp") for short by using the spread operator.
