Built-in function to convert an array of strings to a string

php editor Banana introduces you a very convenient method - the built-in function to convert a string array into a string. During the development process, we often need to merge an array containing multiple strings into one string. In this case, we can use the implode() function. This function accepts two parameters, the first parameter is the separator used to join the array elements, and the second parameter is the array to be joined. By using the implode() function, we can quickly convert a string array into a string, which is convenient for us to use in subsequent processing. The use of this built-in function is very simple, you only need to pass in the corresponding parameters, which is very practical.

Question content

Suppose I have a string like this

stringArray := []string{"Hello"}

I want to convert the array to string so that

s := func(stringArray)

and s should be ["Hello"]

Is there a built-in function in golang that can do this for me?

Solution

Use json library:

import (
    "encoding/json"
)

func toString(arr []string) string {
    b, _ := json.Marshal(arr)
    return string(b)
}

See Live Demo.
