***Must be built using a list, not an array***

Implement a Stack in Javascript (you will turn in a link to your program in JSFiddle). Do not use an array as the stack or in the implementation of the stack. Repeat - You MUST implement the Stack (start with your linked list) without the use of an array..

You will build a Stack Computer from your stack. When a number is entered it goes onto the top of the stack. When an operation is entered, the previous 2 numbers are operated on by the operation and the result is pushed onto the top of the stack. This is how an RPN calculator.

For example

2 [enter] 2

5 [enter]   5 2

* [enter] * 5 2 -> collapses to 10

would leave at 10 at the top of the stack.

The program should use a simple input box, either a text field or prompt and display the contents of the Stack.

Solution

I have written Stack functionality in JavaScript Using prototype.

// Creates a stack . Count variable is to store the count of elements and storage array is used to Store the elements.

var Stack = function() {
    this.count = 0;
    this.storage = {};
}

// Adds a value onto the end of the stack
//This can be processes by increasing the count of elements in the Array and push the element at the back of the Array.
Stack.prototype.push = function() {
    var value = document.getElementByID(\"value\");
    this.storage[this.count] = value;
    //Increase the count of the elements in the Stack.
    this.count++;
}

// Removes the value at the end of the Stack. This Function will also return Popped up element.
Stack.prototype.pop = function() {
    // If the stack is empty we can\'t be able to remove the element so undefined.
    if (this.count === 0) {
        return undefined;
    }
    // Reduce the count of the number of Elements in the Array.
    this.count--;
  
    //Return the removed Element also
    var result = this.storage[this.count];
    delete this.storage[this.count];
    return result;
}

// This function is useful for calculating the size of the Stack.
Stack.prototype.size = function() {
    return this.count;
}
