console.log('addition(5,10) = ' + result);

console.log();

result = math_example.subtraction(50,10);

console.log('subtraction(50,10) = ' + result);

console.log();

result = math_example.multiplication(3,7);

console.log('multiplication(3,7) = ' + result);

console.log();

result = math_example.division(27,3);

console.log('division(27,3) = ' + result);

console.log();

result = math_example.fibonacci(3);

console.log('fibonacci(3) = ' + result);

console.log('done');

This code sets a reference to the math_example package. The code executes a small test of

each of the exported functions. Run the code by executing the following command.

node main

The result is shown in Figure 8-6. Each function returns a result, and then the result is

displayed.
