The stringValueOf task returns the primitive value of a string object as a string data type. Primitive value is data that is stored directly in the location the variable accesses.
This method is rarely used in data manipulation; however, it is useful when you need to convert different types of values into a string.
In this example, the str variable is set to Hello World.
The string is validated and the expected result will be "Hello World" contained within double quotation marks.
