0107. Exclamation marks series #4: Remove all exclamation marks from sentence but ensure a exclamation mark at the end of string

Description:

Remove all exclamation marks from sentence but ensure a exclamation mark at the end of string. For a beginner kata, you can assume that the input data is always a non empty string, no need to verify it.

Examples

remove("Hi!") === "Hi!"
remove("Hi!!!") === "Hi!"
remove("!Hi") === "Hi!"
remove("!Hi!") === "Hi!"
remove("Hi! Hi!") === "Hi Hi!"
remove("Hi") === "Hi!"

Solution:

const remove = (string) => string.replace(/!/g, "") + "!"
