in the double quotations you insert a simple space character, so that the output will be : My name is Newton Volleyman; If you don't put that the output would be: My name is NewtonVolleyman; It is just used to make the output look clear and easy to read

Double quotes(") are only used to print the text in that command. If double quotes aren't used, it will take it as to print the value of that variable.
