Removing Whitespace from Strings in Go: A Swift Solution

When working with strings in Go, it's often necessary to remove whitespace characters. The traditional approach involves chaining two functions from the string package:

response = strings.Join(strings.Fields(response),"")

However, this approach can be slow and inefficient. A more performant method is to utilize the strings.ReplaceAll function, which allows for the substitution of a specific whitespace character with an empty string:

randomString := "  hello      this is a test"
fmt.Println(strings.ReplaceAll(randomString, " ", ""))

This approach effectively strips all occurrences of a single whitespace character from the input string effortlessly. Note that this method can be applied multiple times to remove different types of whitespace, but it is not capable of removing all types of whitespace at once.
