Clojure apply string replace to each element in array

Given an array contains elements such as:

[":test" ":do_this" "dont" ":_another_one"]

I need to remove the : and replace it with a empty string which can be done using:

(clojure.string/replace element #":" "")

However how can I apply this to every element? I have looked at using the apply function but it doesn't seem to modify the elements, is this because they are in fact immutable?

(apply function collection)

Is what I've been looking at doing but no luck so far.

Use map:

(let [input [":test" ":do_this" "dont" ":_another_one"]
      updated (map #(clojure.string/replace % #":" "") input)]
  ...)

this returns a sequence instead of a vector, so use mapv if you want to create a new vector.
