join an array of characters into a string in go

To join an array of characters into a string in Go, you can use the built-in strings.Join() function. Here is an example code snippet:

main.go
package main

import (
    "fmt"
    "strings"
)

func main() {
    charArr := []string{"H", "e", "l", "l", "o"}
    str := strings.Join(charArr, "")
    fmt.Println(str)
}
173 chars
13 lines

In this example, we first define an array of characters called charArr. We then use strings.Join() to join the elements of the array into a single string. The second argument to strings.Join() is the separator string to insert between each element (in this case, the empty string "" is used to join the characters without any separator). Finally, we print the resulting string to the console.

The output of the above code should be:

main.go
Hello
6 chars
2 lines
