Referring to the link above, what big difference does a closure makes when we compare it with a normal function?

From the link above:

"Closures may be 'bound' to variables within the scope where they are defined"

In addition to that, you can pass a closure as an argument to a method. Then that method can call your closure. This means you can give a method some block of code, and the method can execute that block of code.

I'd recommend reading the Formal Definition on the Groovy site.

Yesterday I bought the Groovy in Action book and started working on it already and it seems to be really interesting and now I'm fully exploring the Object Oriented concepts in Java through Groovy.
I agree. Here's the link:
