Remove Last

Removes the last item from an array.

​
Inputs

  • flow: The flow input to trigger the node’s execution.
  • array: The input array to remove the last item from. Defaults to an empty array.

​
Outputs

  • flow: The flow output to continue the execution of the spell.

​
Configuration

This node does not have any additional configuration options.

​
Usage

  1. Connect the flow input to the previous node’s output that triggers the execution.
  2. Connect the array input to an array variable or a node that outputs an array.
  3. Connect the flow output to the next node in the spell’s execution flow.

​
Example

Suppose you have an array of names and want to remove the last name from the list. Here’s how you can use the Remove Last node to achieve this:
  1. Create an array variable with the following names: [“Alice”, “Bob”, “Charlie”, “David”]
  2. Connect the array variable to the array input of the Remove Last node.
  3. Connect the flow output of the Remove Last node to the next node in your spell, for example, a Debug node to log the updated array.
After executing the spell, the Debug node will output the array [“Alice”, “Bob”, “Charlie”], with “David” removed from the end of the list.

​
Best Practices

  • Ensure that the input array is not empty before using the Remove Last node to avoid errors.
  • If you need to remove multiple items from the end of an array, consider using a loop or a custom function node.

​
Common Issues

  • If the input array is empty, the Remove Last node will not modify the array and will simply pass it through to the output.
  • Be cautious when using the Remove Last node in a loop, as it will continuously remove items from the end of the array until the loop condition is met or the array becomes empty.
