Index Array
What It Does
Extracts a single value from a list at a specified position (index). It allows you to retrieve individual elements from an array by their numerical position.
Inputs
| Name | Description | Type | Required |
|---|---|---|---|
| array | The list to extract the value from | List | Yes |
| index | The position to extract (starts at 0) | Number | No |
Outputs
| Name | Description | Type |
|---|---|---|
| value | The item found at that position | Any |
How to Use It
- Drag the Index Array node into your graph.
- Connect an array (like
[Red, Green, Blue]) to the "array" input. - Set the "index" value (default is 0, which returns the first item).
- The output will be the value at that position (e.g., with index 1, the output would be "Green").
Tips
- Array indexes start at 0, so the first item is at index 0, the second at index 1, etc.
- If you use a negative index, it counts backward from the end (-1 is the last item).
