 To run a block of code when a condition is true, use an <code class="language-javascript">if</code> statement.
 
-<pre><code class="language-javascript">    if (condition) {
+```javascript
+if (condition) {
         doSomething();
-    }

 You can also run a block of code when a condition is false using the <code class="language-javascript">else</code> statement.
 
-<pre><code class="language-javascript">    if (condition) {
-        doSomething();
-    } else {

 To run a block of code over and over again until a condition is false, use a <code class="language-javascript">while</code> loop.

 Don’t forget to include something in the loop that will eventually make the condition <code class="language-javascript">false</code>, otherwise you run into an infinite loop. (Which is a loop that never stops repeating itself; most likely crashing your browser)

 If you want to run something a certain amount of times, use a &#8220;<code class="language-javascript">for"</code> loop. For loops can be broken down into three components: an initiating statement, a condition, and a statement that runs after every loop.
 
-<pre><code class="language-javascript">    for (var i = 0; i &lt; 5; i++) {
+```javascript
+for (var i = 0; i &lt; 5; i++) {

 Here you have the initiating statement of <code class="language-javascript">var i = 0</code>. From there you check, is <code class="language-javascript">i</code> less than 5? Yes, so then we <code class="language-javascript">doSomething();</code>. After we <code class="language-javascript">doSomething();</code>, we add 1 to <code class="language-javascript">i</code>. Now <code class="language-javascript">i</code> equals 2. Is <code class="language-javascript">i</code> still less than 5? Yes, so we <code class="language-javascript">doSomething();</code>. Then we add 1 to <code class="language-javascript">i</code> again. This loop will keep happening until <code class="language-javascript">i</code> is not less than 5.

 Having different control/conditional statements helps keep the state of any application you’re making. Did the user say not to notify them? Then don’t, otherwise (else) notify them. That’s all I have to say for this week. Hope this post helps you get a little more used to this big world called programming.

 I recommend that you look at different perspectives of the same concepts. WebCheatSheet.com has a similar post to mine, check out what they had to say [here](http://webcheatsheet.com/javascript/if_else_switch.php).
