<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 faveFruit = [ 'apples', 'bananas', 'kiwi', 'strawberry', 'blueberries', 'peaches', 'mango'];

// Insert your code for #2 here
faveFruit.unshift('blackberries');
console.log(faveFruit);

// Insert your code for #3 here
faveFruit.forEach(function(elem) {
        console.log(elem);
    });

// Insert your code for #4 here
var i;
for (i = 0; i < 100; i++)
if ((i % 2) > 0)
  console.log(i);
