Push array into Nested array javascript

Question

I have some code like this:

var array=[[[[[[1],2],3],4],5],6]

I know how to retrieve the innermost array, but I don't know how to push a new array [0] into the innermost array.

---

Is this possible?

• jfriend00: What is the practical use of this? FYI, whatever strategy you use for reading the inner value of 1, you can just assign another array to that same reference.
• ak_: What is your desired output? What have you tried?
• guyys: @jfriend00 it is making an organized array system with sub-arrays that makes it easier to acheive certain things

Answer 1

I suppose you want to add new inner-most array on the first position. You can use unshift function:

array[0][0][0][0][0].unshift([0]);

• guyys: It says I can accept an answer in 5 min. In the meantime, I tried the code and you seem to be correct

Answer 2

Try this one

var array=[[[[[[1],2],3],4],5],6];
function pushNew(arr, newElement){
 if(arr[0].length === 2){
 pushNew(arr[0], newElement);
 } else {
 arr[0].unshift([newElement]);
 }
}
pushNew(array,0);
