Reactions & Triggers
When this happens, do that — the page's only rule primitive, plus the per-clip triggers in the timeline.
Comparators and operands.
An onCompare reaction takes a path, an operator and a scalar operand — a string, a number, a boolean, or null.
| Op | Meaning |
|---|---|
| eq / ne | Equal / not equal. |
| lt / lte / gt / gte | Numeric or lexical ordering. |
| in / not-in | Membership in a collection. |
| contains | Substring or element containment. |
A timeline trigger's condition is richer: each side can come from page data, page memory, poller data, or a literal value, so one path can be compared against another rather than only against a constant.
