Property Binding in Angular 8
Property Binding is also a one-way data binding technique. In property binding, we bind a property of a DOM element to a field which is a defined property in our component TypeScript code. Actually Angular internally converts string interpolation into property binding.
<img [src]="imgUrl" />
Property binding is preferred over string interpolation because it has shorter and cleaner code String interpolation should be used when you want to simply display some dynamic data from a component on the view between headings like h1, h2, p etc.
Note: String Interpolation and Property binding both are one-way binding. Means, if field value in the component changes, Angular will automatically update the DOM. But any changes in the DOM will not be reflected back in the component.
