<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 myCaptains = ["James T. Kirk", "Jean-Luc Picard", "Katherine Janeway"];


// Insert your code for #2 here
myCaptains.unshift("Jack Sparrow");
console.log(myCaptains);

// Insert your code for #3 here
var arrayLength = myCaptains.length;
for (var i = 0; i < arrayLength; i++)
	alert(myCaptains[i]);
  
	console.log(myCaptains);



// Insert your code for #4 here

for (var i = 1; i <= 100; i++) {
	if((i %2 ) !== 0) 
  	console.log(x + "is odd")
    
    }
