How does array.each element work?

Hi All,

Here is my code snippet:-
my_array = [1,2,3]
puts my_array.each {}

or

my_array = [1,2,3]
my_array.each {|x| puts x}

O/p:-
1
2
3

I want to know how the array.each works. How the compiler interprets and
prints.

Thanks and regards,
Neela.

No, everyone does not have an equal opportunity to succeed. That is what
you wingnuts would like us to believe while simultaneously discriminating
against anybody with dark skin. You GOP cocksuckers are despicable.

each will iterate over each element in the array and then yield to a
supplied block with a single variable, the item in the array.
If you have a look at the C code, you'll see a familiar looking for
loop with calls to yield.

For a better understanding, you need to do some further reading on
blocks in ruby.
