How do you categorize data binding types?
Binding types can be grouped into three categories distinguished by the direction of data flow. They are listed as below,
- From the source-to-view
- From view-to-source
- View-to-source-to-view
The possible binding syntax can be tabularized as below,
| Data direction | Syntax | Type |
|---|---|---|
| From the source-to-view(One-way) | 1. {{expression}} 2. [target]="expression" 3. bind-target="expression" | Interpolation, Property, Attribute, Class, Style |
| From view-to-source(One-way) | 1. (target)="statement" 2. on-target="statement" | Event |
| View-to-source-to-view(Two-way) | 1. [(target)]="expression" 2. bindon-target="expression" | Two-way |
