//Variables

//Exercise #1
//Create 3 variables named: myvar1 myvar2 myvar3
//1.1: Do so using individual declarations
var myvar1;
var myvar2;
var myvar3;
//1.2: Do so using a single declaration
var myvar1, myvar2, myvar3;

//Exercise #2
//Create a variable called myvar4 with an initial value of 10
var myvar4 = 10;

//Exercise #3
//Multiple myvar4 by 2 and store the result in myvar4
myvar4 = myvar4 * 2;

//Exercise #4
//Divide myvar4 by 2 then subtract 2 from it. Store the result in myvar4
myvar4 = myvar4 / 2 - 2;

//Exercise #5
//Create 2 variables and give them the following values:
//myvar5 should equal 10
//myvar6 should equal 5
//5.1: Do so using individual declarations
var myvar5 = 10;
var myvar6 = 5;

//5.2: Do so using a single declaration
var myvar5 = 10, myvar6 = 5;

//Exercise #6
//Multiple myvar5 by myvar6 and store in myvar7
var myvar7 = myvar5 * myvar6;

//Strings

//Exercise #1
//Store your username in a variable called myname
var myname = "Robert"

//Exercise #2
//Append the value of myname to the beginning of the text " is awesome."
//store in the variable mycompliment
//2.1: Do so using the + operator
var mycompliment = myname + " is awesome"
console.log(mycompliment);

//2.2: Do so using a string template
console.log(`${myname} is awesome.`)

//Exercise #3
//Create a variable called myfruit and store the name of a fruit in it
var myfruit = "pineapple";

//Use a template string to tell how myname likes myfruit and store the result in myexclaimation
var myexclaimation = console.log(`${myname} likes ${myfruit}.`)

//Exercise #4
//Create a variable called alphabet listing all letters from a to z
var alphabet = "abcdefghijklmnopqrstuvwxyz";

//Exercise #5
//Get the first character from the alphabet variable
/*var alphextract = alphabet.substring(0,1);
console.log(alphextract); */

//Exercise #6
//Replace 'abc' in the alphabet variable with the text 123
var alphabet2 = alphabet.replace("abc","123");
console.log(alphabet2);

//Exercise #7
//Get the first 5 characters of the alphabet variable
var alphabetstr = alphabet.substring(0,5);
console.log(alphabetstr);

//Arrays

//Exercise #1
//create an array of the numbers 0 through 9
/*
var array1 = [0,1,2,3,4,5,6,7,8,9];
var array2 = [0,1,2,3,4,5,6,7,8,9];
var array3 = [0,1,2,3,4,5,6,7,8,9];
var array4 = [0,1,2,3,4,5,6,7,8,9];
var array5 = [0,1,2,3,4,5,6,7,8,9];
*/


//Exercise #2
//Remove first 3 items from the array
/* array1.splice(0,3);
console.log(array1); */

//Exercise #3
//Remove last 2 items from the array
/* array2.splice(8,2);
console.log(array2); */

//Exercise #4
//Replace the 2nd item with the text 'example'
/* array3.splice (1,2, "example");
console.log(array3); */

//Exercise #5
//Add the letters 'a', 'b', 'c' to the start of the array
//Each letter should be its own item
/* array4.splice(0,0, "a", "b", "c");
console.log(array4); */

//Exercise #6
//Add 'x' 'y' 'z' to the end of the array where each is a new Item then replace the item containing 'x'
//with the text 'banana'
/* array5.splice(10,2, "x", "y", "z");
array5.splice();
console.log(array5); */

//Arrays #2

//Exercise #1
//create an array of the numbers 0 through 9
var array1 = [0,1,2,3,4,5,6,7,8,9];
var array2 = [0,1,2,3,4,5,6,7,8,9];

//Exercise #2
//Remove first 3 items from the array without using .shift()
/* array1.splice(0,3);
console.log(array1);

//Exercise #3
//Remove last 2 items from the array without using .pop()
array2.splice(8, 2);
console.log(array2); */

//Exercise #4
//Replicate exercises #1-3 using a single statement (That is, do not use ;)
removeValFromIndex = [0,1,2,8,9];
for (var i= removeValFromIndex.length-1; i >=0; i--)
    array1.splice(removeValFromIndex[i],1);
console.log(array1);
//PLEASE TELL ME IF THERE'S AN EASIER WAY TO DO THIS CAUSE I DON'T THINK THIS
//IS THE ANSWER YOU WANTED

//Exercise #5
//Replace the 2nd item with the text 'example' without using the assignment operator(=)
array1.splice(1,1,"example");
console.log(array1);

//Exercise #6
//Add the letters 'a', 'b', 'c' to the start of the array without using .unshift()
//Each letter should be its own item
array1.splice(0,0,"a","b","c");
console.log(array1);

//Exercise #7
//Add 'x' 'y' 'z' to the end of the array where each is a new item without using .push()
//then replace the item containing 'x' with the text 'banana' without using the assignment operator(=)
array1.splice(8,0,"x","y","z");
console.log(array1);
array1.splice(8,1,"banana");
console.log(array1);

//SReject07/07/2018
//PRACTICE: functions

//Exercise #1
//Use code comments to detail what each line of the following does:

//function creating reverseText
/* function reverseText(input) {
    var letters = input.split(''), //assigning input.split('') to letters and result to ""
        result = '';

    //takes each character in letters and then adds chr to the result. Assuming chr = character?
    //I'm unfamiliar with this bit here.
    letters.forEach(function (chr) {
        result = chr + result;
    });
    //returns the result of the function from whatever was input into the function
    return result;
}
//logs the following text to the console using the reverseText function as
//namredips doohrobhgien yldneirf ruoy tsuJ
console.log(reverseText('Just your friendly neighborhood spiderman'));
*/


//Exercise #2
//Rewrite Exercise #1 so that instead of defining then calling the function, its uses an IIFE
console.log((function ReverseText(input){
    var letters = input.split(''), //assigning input.split('') to letters and result to ""
    result = '';

//takes each character in letters and then adds chr to the result. Assuming chr = character?
//I'm unfamiliar with this bit here.
letters.forEach(function (chr) {
    result = chr + result;
});
//returns the result of the function from whatever was input into the function
return result;

})("Hi reversetext, I'm dad."));

console.log('Finished');
