+#### Uglify
+If you want to squeeze a little bit more performance out of the serialisation, at the cost of readability in the generated code, you can pass `uglify: true` as an option.
+Note that you have to manually install `uglify-es` in order for it to work. Only version 3 is supported.
+Example:
+```javascript
+
+const stringify = fastJson({
+  title: 'Example Schema',
+  type: 'object',
+  properties: {
+    id: {
+      type: 'integer'
+    }
+  }
+}, { uglify: true })
+
+// stringify is now minified code
+console.log(stringify({ some: 'object' })) // '{"some":"object"}'
+```
