Stack implementation in JavaScript

• First, I start with implementing the class Stack which is used for the stack.
• In order to store the data in the stack, I am using the constructor method to create and initialize the stack. The data variable will hold elements to our stack.
• The push method is used to add elements to our stack.
• The pop method is used to remove the last element from our stack.
• The peek method is used to return the last element in the data property (our array).
• The empty method is used to check if there are any values in the stack.
