Reading through the Polymer 3.0 documentation, I noticed that both curly {{}} and square [[]] brackets are used. If any, what is the difference between these two methods of data-binding?
The documentation states:
Whether data flow goes down from host to target, up from target to host, or both ways is controlled by the type of binding annotation and the configuration of the target property.
- Double-curly brackets ({{ }}) support both upward and downward data flow.
- Double square brackets ([[ ]]) are one-way, and support only downward data flow.
