Answer Posted / Sandeep Kumar Sharma
In JavaScript, both 'undefined' and 'null' are used to represent absence of a value or an empty value. However, they have some differences:
- 'undefined' represents a variable that has been declared but not assigned a value.n- 'null' is explicitly used to indicate no value or an intentional absence of any object value.nn```javascriptnlet myVar;nconsole.log(myVar); // outputs: undefinednlet myNull = null;nconsole.log(myNull); // outputs: null```

Write a main method that prompts the user to enter the starting population, birth and death rates, and the number of years. The input birth and death rates cannot be negative, the starting population cannot be less than 2, and the number of years greater than 0. If the user enters an invalid value, this program will prompt user to re-enter the value until a valid value has been read. When all input values are valid, call on the methods above to compute estimated population and print result.
