<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 months = ["November", "December", "October", "September"];
console.log(months);

// Insert your code for #2 here

months.unshift("January");
console.log(months);

// Insert your code for #3 here

for (var i = 0; i < months.length; i++) {
  console.log(months[i]);
}

// Insert your code for #4 here

for (var i = 0; i <= 100; i++) {
  if (i % 2 != 0) {
    console.log(i + " is odd");
  }
}
