Check If Value In Array In Angular Template

When you're working with Angular templates and need to check if a particular value exists in an array, you might wonder how to efficiently handle this task. Fear not, as this article will guide you through the process in a simple and straightforward manner.

To check if a value is present in an array within an Angular template, you can leverage the `ngIf` directive along with the `Array.includes()` method in your component. Here's a step-by-step breakdown of how to achieve this:

1. Set up Your Component: First, ensure you have an array in your Angular component that contains the values you want to check against. For example, let's say you have an array called `myArray` with elements `[1, 2, 3, 4, 5]`.

2. Use `ngIf` Directive: In your Angular template, use the `ngIf` directive to check if the value exists in the array. To do this, you can create a template reference variable, let's call it `#valueToCheck`.

3. Check Array In Template: Within the template, you can use the `Array.includes()` method to check if the `valueToCheck` exists in `myArray`. Here's an example snippet:

<div>
    <p>The value {{ valueToCheck }} is present in the array.</p>
</div>
<div>
    <p>The value {{ valueToCheck }} is not in the array.</p>
</div>

4. Applying the Logic: In the above example, we use the `*ngIf` directive to conditionally display a message based on whether the `valueToCheck` is found in `myArray`. If the value is found, the first `
