✏️ Note : Both "Jon" and "John" are pronounced the same and usually refer to the same name, but "John" is the more traditional spelling. "Jon" is a more modern or informal variant used more commonly nowadays. Typically, "Jon Snow" refers to the fictional character from Game of Thrones, while "John Snow" refers to the famous English physician known for his work in epidemiology.
