Modern JavaScript from the Beginning - Second Edition - Calculator Challenge

The video tutorial guides viewers through creating a calculator function in programming. The function takes three parameters: two numbers and an operator, which can be addition, subtraction, multiplication, or division. If an invalid operator is provided, the function returns an error message. The tutorial suggests using either if statements or switch statements to handle the operators. The video also includes testing the function with various inputs to ensure it works correctly.

What is the expected output when passing the parameters 5, 2, and 'plus' to the calculator function?
