Access current Array of object's index with objectArray.length not working?

Question

var objArray = []; var object = {};

I am defining every index of the array by adding :

objArray[objArray.length] = object;

And I can access the length of the objArray by doing

objArray.length;

However, if I try to do

objArray[objArray.length],

it gives me undefined.

Why is this?

`objArray.length` will have changed, and it's always 1 larger than the largest index. Use `objArray[objArray.length -1]` to get the last item. — evolutionxbox, May 11 '22 at 12:09

Because indexing of arrays starts with 0, but when there is one element in an array its index is 0 and array length is 1. Try objArray[objArray.length -1] and it will work.
