Example 2: ngfor index

/*
ngFor with index in angular is used here for generating 'li' element till the studentDetails array length.
And also make a note if you are using angular 1 then you have to replace 'let' with '#', but its ok if you are using angular 2 or above.
*/

    <li *ngFor="let student of studentDetails; index as i;" [attr.data-index]="i">
        {{student}}
    </li>
