Deleting array elements in JavaScript - delete vs splice

Question

What is the difference between using the delete operator on the array element as opposed to using the Array.splice method?

For example:

myArray = [\         


        

Answer 1

Currently there are two ways to do this

1. using splice()

   arrayObject.splice(index, 1);

2. using delete

   delete arrayObject[index];

But I always suggest to use splice for array objects and delete for object attributes because delete does not update array length.
