In JavaScript, you can use the `typeof` operator to check if a variable is an object. However, the `typeof` operator does not distinguish between different types of objects (like Array or Regular Object). Here's an example:n```javascriptnif(typeof variable === 'object') {n // variable is an objectn}n```

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.
