<h3>Arrays &amp; Looping</h3>
<h4>4 Tasks for this Practice Set:</h4>
<ol>
    <li>
        Make an Array of strings and assign it to a variable. You may make the strings a list of anything you like and use a variable name of your choice.</li>
    <li>
        Use one of the methods of the Array object to insert a new element to the beginning of your array. Looking through the methods on the Array reference page at <a href="http://www.w3schools.com/jsref/">W3Schools</a> may be helpful. 
    </li>
    <li>
    Using the Array you made in the previous steps, iterate over its elements and write each one to the console.
    </li>
    <li>
        Loop through the integers from 1 to 100 and write each to the console only if it is odd.
    </li>
</ol>

JavaScript

"use strict"; 

// Insert your code for #1 here
var students = ["Tom", "Dick", "Harry"];
students.length
//answer is 3


// Insert your code for #2 here
function myFunction() {
    var havarti = ["LarrySr", "Mike"];
    var gouda = ["LarryJr", "Rob", "Mine"];
    var honorStudents = havarti.concat(gouda); 
    }
//answer is LarrySr,Mike,LarryJr,Rob,Mine



// Insert your code for #3 here
var cumLaude = LarrySr[0],Mike[1],LarryJr[2],Rob[3],Mine[4];
console.log(cumLaude);


// Insert your code for #4 here
var x
for (x in person) {
     += person[1,3] + " ";
}
//answer is Mike,Rob
