JavaScript Mastery from Zero to Hero - Prepare for Coding Interviews - Make Multiple Copies of an Array with the Spread

The video tutorial guides students through an exercise to make multiple copies of an array using the spread operator. It begins with setting up a variable for the number of copies and creating a function to handle the array. The tutorial emphasizes the importance of using iteration and methods to achieve the desired number of copies. Students are encouraged to share their solutions and are given hints to help them complete the task. The video concludes with a reminder to review past lessons if needed.
