Practice Set - Conditionals & Blocks within Braces
HTML
<h3>Conditionals & 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) :

</li>
</ol>
JavaScript
// Insert your code for #1 here
var x = 2;
if (x > 0) { //check if answer is correct
console.log("Variable x is greater that zero");
} else if (x == 0) { //verify to see if x is equal to zero
console.log("Variable x is equal to zero");
} else { //conclude x is less than 0
console.log("Variable x is less that zero");
}
// 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(); // capatalize the captain's name at that array style
console.log("The Captain in Capitals is " + myCaptains[i]); // log to console the captain's name in caps
}
console.log(i + " captains have been capitalized"); // log to console the number of captains in the array
