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".
