Thanks Dave, I should add the semicolon at the end of the function curl braces. The semicolon I was talking about was after the anonymous function like so:

var anonymousFunction = function();  {

At least when I tried to run the code this way I received a syntax error, but maybe I had another error in the code the created that issue. I was trying to recreate the problem in my environment, so I could help answer the question.

Yeah, definitely. That IS a syntax error.

I do not believe you have to call the function inside of itself. Also, after the function() you have a semi-colon which will lead to a syntax error. If you delete the function call inside the curly braces and the semi-colon it should work. For example:

var anonymousFunction = function() {

}

This should work because now the variable is set to that anonymous function, and that function now does nothing.

Hi Matthew,

Excellent answer. You should add a semicolon at the end of the statement:

var anonymousFunction = function () {

};

You won't get a syntax error without the semicolon, but it's technically correct. Because you are assigning a value to a variable you're creating a JavaScript statement and it should end with a semicolon, just like any JS statement:

var a = "apple";
