The element was removed, but the array still has 3 elements, we can see that arr.length == 3.. That's natural, because delete obj.key removes a value by the key.It's all it does. Fine for objects. But for arrays we usually want the rest of elements to shift and occupy the freed place. Adding elements to inner array: We can use simple square bracket notation to add elements in multidimensional array. salary[3][3] = "India"; // It adds "India" at the 4th index of 4th sub-array, // If we print the entire 4th sub-array, document.write(salary[3]); // the output will be : ["EFG", 31, 28000, "India"] // indexing starts from 0 We can use push() method to add elements in the array.
