Angular exception: Can"t bind to "ngForIn" since it isn"t a known native property

📝 Blog Post Title: "Solving the Angular Exception: Can't bind to 'ngForIn' since it isn't a known native property"

Intro: Have you encountered the error message "Can't bind to 'ngForIn' since it isn't a known native property" while working with Angular? Don't worry, you're not alone! In this blog post, we will explore this common issue, provide easy solutions, and help you get your Angular app back on track. Let's dive right in!

Understanding the Problem: The error you're seeing usually occurs when Angular encounters an unrecognized property, specifically 'ngForIn'. In your code snippet, there is a slight mistake in how you use the ngFor directive. Instead of using 'let talk in talks', you should use 'let talk of talks'.

Easy Solution: To fix the error and allow Angular to recognize the 'ngForIn' property, update your code snippet as follows:

@Component({
  selector: 'conf-talks',
  template: `
    <div *ngFor="let talk of talks">
      {{talk.title}} by {{talk.speaker}}
      <p>{{talk.description}}</p>
    </div>`
})
class ConfTalks {
  talks = [ 
    {title: 't1', speaker: 'Brian', description: 'talk 1'},
    {title: 't2', speaker: 'Julie', description: 'talk 2'}
  ];
}

In the updated code, we have changed the syntax from 'let talk in talks' to 'let talk of talks'. This aligns with the proper use of the ngFor directive and should resolve the error.

Why It Works: The 'let talk of talks' syntax is the correct way to iterate over an array using ngFor. By making this adjustment, we ensure that Angular recognizes the 'ngForIn' property as a known native property and can bind it properly.
