How does array.each element work?

ruby-talk
1

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.

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.
