<h3>Conditionals &amp; Blocks within Braces</h3>


<h4>2 Tasks for this Practice Set:</h4>

<ol>
    <li>Use conditionals to create code which outputs a sentence to the console stating whether the variable <i>x</i> is greater to, equal to, or less than zero. It should work for any numeric value of x</li>
    <li>Look at the code in this section, and fix it so that the output is correct. In your console, it should look like this (Hint: it involves braces) :
        <img src="http://courses.dce.harvard.edu/~cscie3/img/captains.png" title="program output" style="width:80%;padding-top:.5em;">
    </li>
</ol>

JavaScript

"use strict";

// Insert your code for #1 here
var x = 0;
if (x < 0) {
 var text1 = "x<0";}
 console.log(text1);
 
if(x == 0){
var text2 = "x=0";}
 console.log(text2)
 
if(x > 0){
var text3 = "x>0";}
 console.log(text3);


// Insert your code for #2 here
var myCaptains = ["James T. Kirk", "Jean-Luc Picard", "Katherine Janeway"];

for (var i = 0; i < myCaptains.length; i++)
myCaptains[i] = myCaptains[i].toUpperCase();
console.log("The Captain in Capitals is " + myCaptains[i]);
console.log(i + " captains have been capitalized");
