+# es3ify
+
+Browserify transform to convert quote reserved words in property keys for compatibility with ES3 JavaScript engines like IE8. In addition, trailing commas in array and object literals are removed.
+
+```javascript
+// In
+var x = {class: 2,};
+x.class = [3, 4,];
+
+// Out:
+var x = {"class": 2};
+x["class"] = [3, 4];
+```
+
+Run tests with:
+
+```sh
+npm install -g jasmine-node
+jasmine-node spec
+```
