Immediately invoked functional expressions

- [Narrator] In the previous example,…I treat the variable containing the anonymous function…as if it were a function itself.…You see it right here, I'm calling the variable name,…then adding parenthesis after it, pretending its a function,…and then passing arguments into that parenthesis.…These arguments are then passed…to the anonymous function inside the variable,…the function runs, some result is returned,…and then we're console logging the result…as if everything here was a function.…It begs the question, what happens…if we just console log out the variable itself?…Well, let's try it.…

Save that, and you see we actually…get the function in the console.…This is important, because later…we'll hook up anonymous functions to events,…and in that case, we actually want…the function to be returned, not the result of the function.…More on that later in the course.…This scenario brings up an important question:…How do I populate the variable…with the result of an anonymous function?…The answer is you need to use…an immediately invoked function expression…
