However, instead of immediately printing strings out, we will explore the various things you can do to them. You can also use single quotes to assing a string. However, you will face problems if the value to be assigned itself contains single quotes.For example to assign the string in these bracket(single quotes are ' ') you need to use double quotes only like this.
