Why does Array#each return an array with the same elements?

I'm learning the details of how each works in ruby, and I tried out the following line of code:

p [1,2,3,4,5].each { |element| el }

And the result is an array of

[1,2,3,4,5]

But I don't think I fully understand why. Why is the return value of each the same array? Doesn't each just provide a method for iterating? Or is it just common practice for the each method to return the original value?

each self ruby arrays

If you want, for some reason, to suppress the output (for example debugging in console) here is how you can achive that

  [1,2,3,4,5].each do |nr|
    puts nr.inspect
  end;nil
