Fork this repository to your GitHub account, then clone your GitHub copy onto your computer. Write the functions assigned below in the file functions.js. Use snippets to run and observe the results of your code.

Here's how to use a snippet:

1. Open the Chrome Developer Console (Option + Command + I)
2. Navigate to the Sources tab in the Chrome Developer Console.
3. Click on the Snippets tab within the Sources display.
4. Right-click and choose New to create a new Snippets file.
5. Name the Snippets File myFunctions.
6. Write or paste code into the editing window and press cmd + return to run the code.

You'll be filling in a bunch of empty function definitions. Type each blank function definition into the snippet, then you write the rest of the code to make the function work.

After you implement a function successfully in your snippet, copy it over into the functions.js file. Unless a different behavior is specified, have the function log the answer to the console AND return it.

Notice there is a solutions.js file. Make a full attempt at finishing these on your own and refer to the solutions only when you are finished or unbearably stuck. Also recognize that the solutions are only one solution and that there are many good ways to solve these problems.

For some of the problems, you'll have to use functions or other variables supplied by JavaScript's built-in Math object. Here is the documentation on using the Math object.

Example Usage of Math

	var absoluteValue = Math.abs(-4);
	// evaluates to 4

	var fourSquared = Math.pow(4, 2);
	// evaluates to 16

	var roundedToNearestInteger = Math.round(1.22343);
	// evaluates to 1

When you wrap up work, edit this README to include your name, a link to the original repository, and a 3-5 sentence reflection on completing this assignment. Example:

I was a able to complete all of the mathematical functions, but the string related functions were difficult for me. I spoke with the evening TA and she helped me solve the ASCII triangle function. I'm still feeling iffy on writing my own loops.

Return a new string that is the combination of two arguments passed into the function

Example: dog and house will display doghouse

function combineWords(word1, word2) {
	// TODO: Place your code here
}

var result = combineWords('dog', 'house');
console.log(result);
// displays 'doghouse'

Display an argument phrase to the console n times

function repeatPhrase(phrase, n) {
	// TODO: Place your code here
}

repeatPhrase("Hello", 5);
// displays
// Hello
// Hello
// Hello
// Hello
// Hello

Return number ^power without using built-in Math functions

Example:
4⁵ = 4 * 4 * 4 * 4 * 4 = 1024

function toTheNthPower(number, power) {
	// TODO: Place your code here		
}

var result = toTheNthPower(4, 5);
console.log(result);
// displays 1024

Return the area of a circle given the radius
background information

function areaOfACircle(radius) {
	// TODO: Place your code here
}

var result = areaOfACircle(2);
console.log(result);
// displays approximately 12.57

Return c given a and b
background information

function pythagoreanTheorem(a, b) {
	// TODO: Place your code here
}

var result = pythagoreanTheorem(3, 4);
console.log(result);
// should display 5;

Return a boolean value whether or not X can be divided by Y without any remainders.

Hint: Explore the world of Modulus operators!

function isXEvenlyDivisibleByY(x, y) {
	// TODO: Place your code here
	if (x % y === 0) {
		 return true;
 	}
 	return false;
}

var result = isXEvenlyDivisibleByY(99, 3);
console.log(result);
// displays true

Return the number of occurrences of vowels in a word. Vowels are a, e, i, o, u, and y

function countVowels(word) {
	// TODO: Place your code here
}

var result = countVowels("stealing");
console.log(result);
// displays 3

Challenge: Can you alter the code to count both upper case AND lower case?

Given an array, return true if it contains the string "wdi" and false if it does not contain that string.

Example:

findWdi([9,'Bart Simpson', true, 'wdi']) // returns true
findWdi(['a','b','c']) // returns false

	function findWdi(arr){
		// TODO: Place your code here
	}

Display a simple triangle with asterisks

Example:
printTriangle(5)

*
**
***
****
*****

function printTriangle(length) {
	// TODO: Place your code here
}

printTriangle(3);
// displays
// *
// **
// ***

Example: printPyramid(10);

           *
          * *
         * * *
        * * * *
       * * * * *
      * * * * * *
     * * * * * * *
    * * * * * * * *
   * * * * * * * * *
  * * * * * * * * * *

Warning: This is a surprisingly tricky interview-level exercise. Try at your own risk!

function printPyramid(length) {
	// TODO: Place your code here
}
