Count
What It Does
Calculates the number of items in an array. It simply returns the length of the input array, regardless of what type of items the array contains.
Inputs
| Name | Description | Type | Required |
|---|---|---|---|
| value | The array to count items in | List | Yes |
Outputs
| Name | Description | Type |
|---|---|---|
| value | The number of items in the array | Number |
How to Use It
- Drag the Count node into your graph.
- Connect an array (like
[4, 5, 6, 7]) to the "value" input. - Run the graph—with the example array, your output will be 4.
Tips
- Works with any type of array (numbers, strings, colors, mixed types, etc.).
- Empty arrays will return 0.
- This node counts only the top-level items; it doesn't count items in nested arrays.
