| Node | A unit of functionality that can be connected to other nodes in a flow. Nodes can becode (with functionality written in JavaScript or TypeScript) or a visual node, which is a group of other nodes (visual or code) arranged in a "nodes and wires" style. | |
| Grouped node | A node that is made up of other nodes arranged in a "nodes and wires" style. | |
| Code node | A node with functionality written in JavaScript or TypeScript. | |
| Input pin | A pin on a node that receives data. Each node can have zero or more input pins. | |
| Output pin | A pin on a node that sends data. Each node can have zero or more output pins. For example, a "Split array" node might have one input pin for an array and two output pins for the first and second halves of the array. | |
| Main flow input/output pin | Special input/output pins that are used to pass data into or out of the main flow. These are typically used to pass data between the main flow and external code (e.g. a user interface). | |
| Connection | A link between two pins that allows data to flow from one node to another. | |
| Reactive inputs | Input pins that trigger the node to execute whenever their value changes. | |
| Completion outputs | Output pins that indicate when the node has finished executing. These are typically used to coordinate the flow of data between nodes | |
