Is possible to combine two arrays? "array.join(array)"?

Question

I have two arrays:

var array1= [[1],[2],[3]];
var array2= [[10],[20],[30]];

is there a way to (have) a third array?

var array3 = [[1],[10],[2],[20],[3],[30]];

Maybe:

var test= array1.join(array2 + "<br>");

Question marks: 1 or 0, not an arbitrary number. – user229044 Jul 12 '14 at 22:56 — user229044, Jul 12 '14 at 22:56

I think you are looking for the "concat" function

Join two arrays:

var hege = ["Cecilie", "Lone"];
var stale = ["Emil", "Tobias", "Linus"];
var children = hege.concat(stale);

The values of the children array will be:

Cecilie,Lone,Emil,Tobias,Linus

no concat.... combine. In yuor case, i want "celie, emil, lone, tobias. – Borja Jul 12 '14 at 22:58
Note, if want to do a safe concat you'd do `hege.concat([stale])` – elclanrs Jul 12 '14 at 22:58
@elclanrs: That would give an undesirable result. `["Cecilie", "lone", ["Emil", "Tobias", "Linus"]]` – cookie monster Jul 12 '14 at 23:02
@cookiemonster: right... I was thinking of a different case. `concat` has some gotchas... – elclanrs Jul 12 '14 at 23:04
@cookiemonster infact.... – Borja Jul 12 '14 at 23:04
@user3163117 Sorry, haven't payed enough attention to your question. Well, i never saw such a function that do what you want. But I believe that a single loop would do the job. – Peterson Jul 12 '14 at 23:04
@user3163117: This answer will do exactly what your question describes. – cookie monster Jul 12 '14 at 23:06
i want ["Cecilie", "Emil", "Lone", "Tobias"]. No ["Cecile, "Lone", "Emil", "Tobias"] (with concate). – Borja Jul 12 '14 at 23:07

@user3163117: Oh, you want it zipped. Simple enough with a loop. Start writing some code. – cookie monster Jul 12 '14 at 23:08
@elclanrs Should I always use (or prefer to use) the mozilla developer network for references on answers? – Peterson Jul 12 '14 at 23:09
@Foca: W3Schools has bad reputation in SO, for good reasons. I'd prefer to see MDN links, the info is just better, and the examples are more in-depth. – elclanrs Jul 12 '14 at 23:10
with loop is possible ? how please ? – Borja Jul 12 '14 at 23:12

You can either use CONCAT function like

array1 = array1.concat(array2)

OR, APPLY()

array1.push.apply(array1, array2)

not function, and it is not a "concat" the true way.... :/ – Borja Jul 12 '14 at 23:11
You say so cause probably the order in which the items to be as in your posted code. Right? You can use a `for` loop and get the item combined but I am not sure about the order though. – Rahul Jul 12 '14 at 23:15
