 TrimKit is a set of DOM and API abstractions for the purpose of better Javascript minification. For
 example:
 
-    if (a === undefined) { alert('Oops'); }
+```
+if (a === undefined) { alert('Oops'); }
+```
 
 minifies down to:
 
-    if(a===void 0){alert('Oops')}
+```
+if(a===void 0){alert('Oops')}
+```
 
 If we compare against undefined more than 3 times, we can save bytes by doing this:
 
-    function isUndefined(a) { return a === void 0; }
+```
+function isUndefined(a) { return a === void 0; }
 
-    if (isUndefined(a)) { alert('Oops'); }
+if (isUndefined(a)) { alert('Oops'); }
+```
 
 which minifies down to:
 
-    function b(a){return a===void 0}
+```
+function b(a){return a===void 0}
 
-    if (b(a)){alert('Oops');}
+if (b(a)){alert('Oops');}
+```
 
 With enough uses of common APIs, you can win back some bytes.
 
 NOTE: TrimKit will help you obsess about Javascript file sizes but that does not always translate to
 smaller files after you apply compression. Because files using have more entropy, small,
-pre-compression gains can result in after compression losses. YMMV.
+pre-compression gains can result in post-compression losses. YMMV.
