Lab Task:

Title: Manipulating Arrays and Objects in JavaScript

Write code in JAVASCRIPT:

Create an array of 5 student objects, each containing the following properties: name, age, and subject.

Write a function to add a new student object to the end of the array.

Write a function to remove the student object at a specified index.

Write a function to update the subject of a specified student object.

Write a function to create a shallow copy of the array and store it in a new variable.

Write a function to create a deep copy of the array and store it in a new variable.

Use console.log to display the original array, shallow copy, and deep copy.

Note: You can use the Array.prototype.slice method for shallow copying, and JSON.parse(JSON.stringify(obj)) for deep copying.
