Condition in *ngFor

Question

I have two string arrays and I want to iterate through one of them depends on condition. How can I avoid code duplication? Now *ngIf for now:

<tr *ngIf="!condition">
    <td *ngFor="let field of firstArray">{{field}}</td>
</tr>
<tr *ngIf="condition">
    <td *ngFor="let field of secondArray">{{field}}</td>
</tr>

Is there a better way?

Answer 1

<tr>
    <td *ngFor="let field of (condition ? secondArray : firstArray)">{{field}}</td>
</tr>
