Calling Functions

In the previous exercise, you may have noticed that when we define a function and run the code, nothing happens. That's because the function runs only when we call it. We call a function by its name followed by parentheses. For example, if we have a function defined as follows:

function myFunction() {
    console.log("This is my function");
}

We can call it as follows:

myFunction(); // Prints: This is my function

When we call a function, its body is executed. In this case, This is my function is printed. Functions can be called repeatedly and whenever needed within the program.
