-In C++ and Java, compiling the code gives you _some_ level of protection against misusing variables based on their type information.  JavaScript is loosely typed and therefore doesn't offer this safety.  This makes writing JavaScript more error prone as it's _one more thing_ to mess up.

-# Typechecking Your Javascript
+## Typechecking Your Javascript
 
 So you'd like to compile your JavaScript!
 
 Maybe you're working on a page that looks like this:
 
-```
+```html
 <script src="other_file.js"></script>
 <script src="my_product/my_file.js"></script>
 ```
 
 Where `other_file.js` contains:
 
-```
+```javascript
 var wit = 100;
 
 // ... later on, sneakily ...
 
 wit += ' IQ';  // '100 IQ'
 ```
 
 and `src/my_product/my_file.js` contains:
 
-```
+```javascript
 /** @type {number} */ var mensa = wit + 50;
 alert(mensa);  // '100 IQ50' instead of 150
 ```
 
 In order to check that our code acts as we'd expect, we can create a
 
 ```
 my_project/compiled_resources.gyp

-In your browser, the source map can be loaded through the Chrome DevTools context menu that appears when you right click in the compiled JavaScript source body. A dialog will pop up prompting you for the path to the source map file. Once the source map is loaded, the uncompiled version of the JavaScript will appear in the Sources panel on the left. You can set break points in the uncompiled version to help debug; behind the scenes Chrome will still be running the compiled version of the JavaScript.
