Golang strings.ToTitle Function

The strings.ToTitle function in Golang is part of the strings package and is used to convert a string to title case. In title case, each letter is converted to its title form, which often means that every letter in the string is capitalized. This function is useful for formatting text, particularly when you want to ensure that all characters in a string are in uppercase, such as when processing headings, titles, or names.
