    Intro to JavaScript Functions

Please follow the instructions below.


Download functions.js and save it to the js folder within the ~/vagrant-lamp/sites/codeup.dev/public folder on your Mac.


Create an HTML file named functions_js.html in your public directory.
<!DOCTYPE html>

<html>

	<head>
	
		<title>3.4 Functions</title>
		
		<meta charset="utf8">

	</head>


	<body>

		<script src="functions.js"></script>
	</body>

</html>


Add a <script> tag to your HTML to link up functions.js to your file.


Open functions.js in Sublime and follow the instructions marked TODO:.
"use strict";

var myNameIs = 'Anna'; // TODO: Fill in your name here.

// TODO:
// Create a function called 'sayHello' that takes a parameter 'name'.
// When called, the function should log a message that says hello from the passed in name.
function sayHello(someName){
	console.log("hello "+someName+"!");
}

// TODO: Call the function 'sayHello' passing the variable 'myNameIs' as a parameter.
sayHello(myNameIs);


// Don't modify the following line
// It generates a random number between 1 and 100 and stores it in random
var random = Math.floor((Math.random()*100)+1);

// TODO:
// Create a function called 'isOdd' that takes a number as a parameter.
// The function should use the ternary operator to log a message.
// The log should tell the number passed in and whether it is odd or not.
function isOdd(num){
	var msg = (num%2==0) ? num+" is even steven!": num+" - it's an odd'n";
	console.log(msg);
}

// TODO: Call the function 'isOdd' passing the variable 'random' as a parameter.
isOdd(random);


Finally, save your work, commit the changes to your git repository, and push to GitHub.
