How to invoke callback function

function makeMeal(meal, cb) { alert(Preparing ${meal}.); //answer goes here; }

makeMeal('lunch', () => { alert('Finished the meal!'); });

The above is code for one of the quizzes and it's the only question I cannot get right. I feel like I'm overthinking it, but I'm not sure how to invoke the makeMeal function.

Invoking a function is just a matter of writing the function name with parentheses after it.

In this case, the parameter "cb" represents the function, so to invoke it you would write :point_right: cb()

Yup, I was overthinking it. Thank you so much!
