Array Length
What It Does
Counts how many items are in a list and returns that number. It's perfect for determining the size of collections or arrays.
Inputs
| Name | Description | Type | Required |
|---|---|---|---|
| array | The list to count items in | List | Yes |
Outputs
| Name | Description | Type |
|---|---|---|
| length | The number of items in the list | Number |
How to Use It
- Drag the Array Length node into your graph.
- Connect your list (like
[Red, Green, Blue]) to the "array" input. - The output will be the number of items in the list (e.g., 3).
Tips
- An empty array will return 0.
- This node only counts top-level items; it doesn't count elements in nested arrays.

- Index Array: For accessing specific items in a list by their position.
Use Cases
- Dynamic Sizing: Use the length to calculate scalable spacing based on the number of elements.
- Limit Checking: Verify if a token collection has the expected number of items.
- Conditional Logic: Create different behaviors based on how many items exist in a collection.
