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?

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. — jfriend00

@jfriend00 it is making an organized array system with sub-arrays that makes it easier to acheive certain things — guyys

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]);

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);
