// 1. Declare a variable "myArray" and reference an array of 3 values (colors?)
var myArray = [1,2,3];
var myArray = ["red", "green", "blue"];
var myArray = new Array("red", "green", "blue");

// 2. Declare a variable "person" and reference an object with 2 properties, "name", which is your name, and "toString", which is a function that returns the name value.
var person = {
    name: "Basha shaik",
    toString: function() {
         return this.name;   
    }
};

person.toString();

// 3. Create a function that returns either "elf" or "dwarf", based on a random number
// If less than 0.5, return "elf"
// If more than or equal to 0.5, return "dwarf"

function elfordwarf() {
 
    if (Math.random() < 0.5) {
        return "elf";
    } else {
        return "dwarf";
    }
    
}

console.log(elfordwarf());


// 4. Create a function that iterates over an array and logs each value to the console. Invoke the function passing "myArray" (from above) as the argument.

var arrayIterator = function(arr) {
     
    for (var i=0; i<arr.length; i++) {
         console.log(arr[i]);   
    }
    
}

arrayIterator(myArray);


// 5. Create a new object called "me" that uses "person", the object you created up above, as its prototype.
var me = Object.create(person);

// 6. "call" your "toString" function from the "person" object in the context of the "me" object.

console.log(person.toString.call(me));
