Chapter 9 talks a tiny bit about arrays. End on the component in regards to the Math package deal. We will take a look at that later.
is The mixture of a perform and the lexical environment in just which that function was declared. This ecosystem consists of any area variables that were in-scope at enough time the closure was developed. In this case, myFunc is actually a reference towards the occasion with the functionality displayName designed when makeFunc is operate.
