# Helper Nodes

Helper Nodes in Blup are essential for enhancing your application's logic and functionality. They provide specific actions on variable nodes, making data management and manipulation easier.

## Helper Nodes Overview

This section includes helper functions for handling variables. These functions assist in performing specific actions on variable nodes.

For additional details, you can navigate directly to the desired nodes by clicking on the respective node below.

1. [Integer Node](/wiki/logics/helper-nodes/integers-nodes.md)
   * Manages whole numbers.
   * Useful for mathematical operations and counters.
   * [Learn more](https://docs.blup.in/wiki/logics/helper-nodes/integers-nodes)
2. [Double Node](/wiki/logics/helper-nodes/double-nodes.md)
   * Handles decimal numbers.
   * Ideal for precise calculations.
   * [Learn more](https://docs.blup.in/wiki/logics/helper-nodes/double-nodes)
3. [Boolean Node](/wiki/logics/helper-nodes/boolean-nodes.md)
   * Manages true/false values.
   * Essential for decision-making logic.
   * [Learn more](https://docs.blup.in/wiki/logics/helper-nodes/boolean-nodes)
4. [Date-Time Node](/wiki/logics/helper-nodes/date-time-nodes.md)
   * Deals with dates and times.
   * Useful for scheduling and time-sensitive operations.
   * [Learn more](https://docs.blup.in/wiki/logics/helper-nodes/date-time-nodes)
5. [Json Node](/wiki/logics/helper-nodes/json-nodes.md)
   * Manages JSON data structures.
   * Vital for handling complex data formats and APIs.
   * [Learn more](https://docs.blup.in/wiki/logics/helper-nodes/json-nodes)
6. [List Node](/wiki/logics/helper-nodes/list-nodes.md)
   * Manages lists of items.
   * Useful for array-like data operations.
   * [Learn more](https://docs.blup.in/wiki/logics/helper-nodes/list-nodes)
7. [Map Node](/wiki/logics/helper-nodes/map-nodes.md)
   * Handles key-value pairs.
   * Ideal for dictionary-like data structures.
   * [Learn more](https://docs.blup.in/wiki/logics/helper-nodes/map-nodes)
8. [String Node](/wiki/logics/helper-nodes/string-nodes.md)
   * Manages text data.
   * Useful for string manipulations and text operations.
   * [Learn more](https://docs.blup.in/wiki/logics/helper-nodes/string-nodes)
9. [Duration Node](/wiki/logics/helper-nodes/duration-nodes.md)
   * Handles time durations.
   * Useful for operations involving time intervals and delays.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.blup.in/wiki/logics/helper-nodes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
