Closures are very important because they help us to write asycrinous code. What I understand is that when a function that has a closure as a parameter will only perform the code inside the curly braces when the task that you passed when declared that function had been finished.Hope you understand, I am on my phone right now so it is impossible to answer with some examples

Thank you very much lgor
