​
Concat

The Concat node combines three input arrays into a single output array in the order the inputs are provided.

​
Inputs

  1. a (array): The first array to concatenate. Default value is an empty array.
  2. b (array): The second array to concatenate. Default value is an empty array.
  3. c (array): The third array to concatenate. Default value is an empty array.

​
Outputs

  1. result (array): The array resulting from concatenating the a, b, and c input arrays in order.

​
Configuration

This node has no configuration options.

​
Usage

To use the Concat node:
  1. Add the Concat node to your spell.
  2. Connect arrays to the a, b, and c input ports as desired. Any or all of the inputs can be left empty.
  3. The concatenated array will be output from the result port.

​
Example

Let’s say you have three separate arrays with names, job titles, and departments in your company directory: 
names = ["Alice", "Bob", "Carol"]
titles = ["Software Engineer", "Product Manager", "UX Designer"] 
departments = ["Engineering", "Product", "Design"]
Connecting these to the a, b, and c inputs of the Concat node will output: 
result = [
  "Alice",
  "Bob", 
  "Carol",
  "Software Engineer",
  "Product Manager",
  "UX Designer",
  "Engineering",
  "Product",
  "Design"
]

​
Best Practices

  • The order of the concatenated arrays will match the order of the inputs. Put the arrays in the desired sequence.
  • It’s not required to connect arrays to all three inputs. Any empty inputs will simply be ignored.
  • The input arrays don’t need to be the same length. The output will contain all elements from each.

​
Common Pitfalls

  • Be cautious of accidentally duplicating data if the same array is connected to multiple inputs.
  • Note that this node does not do any sort of merging of the arrays. The output is a simple concatenation.
