Enhancing Data Integrity in Angular: Using Radio Button and Checkbox to Ensure Unique Array Values

When working on Angular applications, maintaining data integrity is vital. One common scenario developers encounter is ensuring that only selected values are added to an array without any duplication. This can be efficiently achieved using radio buttons and checkboxes.

Importance of Preventing Duplication

In any application, data accuracy plays a crucial role. Allowing duplicate data can lead to inconsistent results, incorrect data processing, and overall poor user experience. Therefore, it's essential to prevent such occurrences by implementing robust selection mechanisms.

Leveraging Radio Buttons and Checkboxes

Radio Buttons

Radio buttons are typically used when a user needs to select only one option from a predefined set. This can be useful in scenarios where a single choice needs to be saved without repetitions. Angular provides an easy way to bind radio button values to a model which ensures the selected value is always unique.

How to Implement

Create the Model:
Define a model in your component to hold the selected value.
