Instructions

Implement the following in the error-handling.js file.

1. sum function is throwing an error! Determine why the error is thrown, and handle only that particular error type using try...catch. Print the error message if the code is throwing the error type you expect
2. Create sayName(name) function that will print the name that is passed to it if name argument is a string. It should throw a TypeError with a message of "Invalid name! Must be a string!" if name is not a string. Run the sayName function test cases inside of try...catch and print out the error message if an error is thrown.
3. Come up with a test case that will cause the greeting function to throw the Error. When an error is thrown from that test case, catch it and print out "Hello World!"
