How to remove the last character of a string in Golang?

Question

I want to remove the very last character of a string, but before I do so I want to check if the last character is a \"+\". How can this be done?

Answer 1

No builtin way. But it's trivial to do manually.

s := "mystring+"
sz := len(s)

if sz > 0 && s[sz-1] == '+' {
    s = s[:sz-1]
}
