Node
A Node is a Block that composes a Flow. It is the name for a Block in a specific usage environment.
When you place one or more Blocks in the Flow editor:
These Blocks in the Flow are called Nodes. A Block itself can be seen as an encapsulated functionality, but it has no meaning and cannot be executed if it is not used in a specific working environment.
Therefore, Blocks in a Flow take on the functionality of a specific part of the business process, and at this point they become executable Nodes.
Except for script Nodes, editing Nodes in a Flow does not directly affect the properties and code of the Block itself. Each Node can be considered as a copy that references the Block, and does not affect the original Block definition.
Only script Blocks are special. Script Blocks, as a means to quickly start editing code, are created and used directly in the Flow, so they have both Node and Block configuration properties.
Editing the properties of a script Node is editing the Block itself, and each script Node is independent of each other.
