Based on array length create a concat string using javascript

Question

I have

array.length=3
array2=['[A]','[B]','[C]','[D]'];

based on array.length, i want to create set of string
example, if lenght=3
output= [A][B][C]

example, if lenght=2
output= [A][B]

i tried using for loop but it prints vertically and could not store and append ,I have no idea how to print horizontally,any ideas or help would be really appreciated
my output is

[A]
[B]
[C]
AND Then i store it in variable and tried appending them. I know this is not the best idea

"i tried using for loop but it prints vertically and could not store and append" - this doesn't make a lot of sense. — Andy

Try

console.log(array2.slice(0, array.length).join(''));

Though I don't see any point in having the first array. You could use just var len = 3;.
