 This option is to signal `serialize()` that we want to do a straight conversion, without the XSS protection. This options needs to be explicitly set to `true`. HTML characters and JavaScript line terminators will not be escaped. You will have to roll your own.

 #### `options.ignoreFunction`
 
 This option is to signal `serialize()` that we do not want serialize JavaScript function. 
 Just treat function like `JSON.stringify` do, but other features will work as expected.
 
 ```js
-serialize(obj, {unsafe: true});
+serialize(obj, {ignoreFunction: true});
