Change Detection
Noun · Development
Definitions
The mechanism by which a framework or system determines that some state has changed and dependent work such as re-rendering, recomputation, synchronization, or event emission should happen. Different change detection strategies trade off performance, predictability, and how much work developers must do manually.
In plain English: Figuring out when state has changed so the system can update the right things.
Example: "The UI lag came from overly broad change detection that re-rendered the whole dashboard every time one row updated."
