# Advanced Rules Mode

### Rules in Advanced Mode

In advanced rules, you can write conditions and actions in javascript language.

In this javascript code, it is possible to call some defined functions to execute the same actions that you can do in easy mode. On the other hand, we also have some help functions. We will explain them below.


The main function will receive a flattened entity representation, adding the _\_received_ and _\_previous_ values to each datastream. The _\_received_ field is a simple object in provision datastreams and an array object in any other case.

We will use the following entity as an example:

```javascript
entity = {
  "provision.administration.channel": {
    "_value": {
      "_current": {
        "value": "battery_channel",
