JavaScript

/**
 * Exercise:
 * Get to know your data types and variables
 *
 * Follow the directions below but feel free to experiment and veer off course.
 * Work in the console directly OR use "console.log()" to output to the console from the script.
 */

// 1)
// Declare 2 to 5 variables (name them as you like)
// Make at least one string, one number and one boolean. 
// Log the typeof each to the console
    var strExample = "My String";
    var i = 10;
    var flag = true;
    
// 2)
// Declare a new variable that stores the result of a mathematical expression
// You can add/multiply/divide/modulo any set of numbers 
// Log the result to the console
    var result = i + 10;
    console.log("Addition : "+result);
// 3)
// Combine at least three strings together
// Log the result to the console
        console.log(strExample+" I am logging on "+"Console");
// 4)
// Create an array with at least 5 values stored inside
// Log the result to the console
        var arr1 = [1,2,3,4,5];
        var arr2 = [6,7,8,9,10];
        console.log(arr1);
        console.log(arr2);
// 5)
// Use Array.prototype.concat to add another array to your original array
//  var arr3 = arr1.concat(arr2);
// Log the result to the console
        var arr3  = arr1.concat(arr2);
        console.log(arr3);
// 6) 
// Create an object literal that represents a person (perhaps you!)
// Define several properties within the object (name, hairColor, age, etc..)
// Define a property that stores an array ("siblings" or "favoriteColors")
// Log the object to the console
// Then Log ONLY the "name" property to the console
// Then Change the "name" property to something else, then log the object to the console
var myObj = {
    name: "Bala",
    age: 30
};

myObj.name = "Raju";
myObj.lastName = "Gujjari";
console.log(myObj);
// 7) Bonus
// Add a function (method) to the previous object you created to allow it to "speak" to the console. The function should expect a string argument and output "<object.name> said:...
