Angular 2 - get last 5 records from database

Issue

how can I get last 5 records from database?

logs.component.html

<table class="table table-striped table-bordered">
        <thead>
            <tr>
                <th>Date</th>
                <th>Logging in is completed?</th>   
            </tr>
        </thead>
        <tbody> 
                <tr *ngFor="let log of logs">

                        <td >{{log.date}}</td>
                        <td >{{log.isCompleted}}</td>

                </tr>

        </tbody>
</table>

With above code I get all records. I would like to do something similar to:

for(int i=logs.length();i>logs.length()-5;i--)

Solution

I did it that way:

  <tr *ngFor="let log of logs; let i =index">

                    <td *ngIf ="i>=logs.length -5">{{log.date}}</td>
                    <td * ngIf="i>=logs.length -5">{{log.isCompleted}}</td>

            </tr>
