to push an object into a specific index of an array in javascript, you can use the `splice()` method. the `splice()` method changes the contents of an array by removing or replacing existing elements and/or adding new elements in place.

here's a step-by-step tutorial along with a code example:

1. create an array of objects:

2. create the object you want to push into the array and specify the index where you want to insert it:

3. use the `splice()` method to insert the object at the specified index:

4. check the updated array:

the above code will output:

in this example, the object `{ name: 'david', age: 40 }` was inserted at index 1 in the `myarray` array, shifting the existing elements to the right.

remember, the `splice()` method modifies the original array in place. if you want to keep the original array intact, you can create a copy of the array before using `splice()`:

this way, `myarray` remains unchanged, and you can work with `myarraycopy` instead.
