The difference between?property binding?(using?[]) and?string interpolation?(using?{{}}) in Angular.
- Property Binding ([]): Property binding is used to set an element’s property (such as?src,?value,?disabled, etc.) based on a value from the component. It manipulates the?DOM?after the HTML has been processed by the browser. The value provided in the binding expression is evaluated and assigned to the specified property. Data types are preserved because it’s not string interpolation. Example:?<img [src]="imgSrc">?sets the?src?property of the image object. You can’t mix?[]?and?{{}}?on the same attribute.
- String Interpolation ({{}}): String interpolation is a form of?template expression. It replaces the HTML string with the results of the binding and then evaluates the HTML. It’s like replacing placeholders with actual values. Example:?<h1>{{title}}</h1>?displays the value of the?title?property. Useful for displaying text content within elements.
- Why Use Each? Use?{{}}?for simple text content within elements (like headings, paragraphs, etc.). Use?[]?for binding to properties (like setting image sources, enabling/disabling buttons, etc.). Reactive forms use?[]?for?formControlName?because it directly manipulates the form control property.
These bindings helps you create more effective templates and avoid unnecessary debugging hours!
