Why does the array look like this after concatenation?

• 0
  
  
  1.2 console output of regular arrays
  3 outputting their concatenation
  there are some gaps and it looks strange
  why is that?
  
  how did the concatenation:
  array3 = array1.concat (array2)

  Arrays don't look like anything at all. This is an abstraction.
  
  
  
  What you see is the node's attempt to show the array "nicely".
