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

Array Length Example

How to Use It

1. Drag the Array Length node into your graph.

2. Connect your list (like [Red, Green, Blue]) to the "array" input.

3. 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.

See Also

• 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.
