Angular 21 Tutorial in Hindi #22 | Contextual Variables | $index, $count, $first, $last, $even/$odd

In this video, we explore Contextual Variables inside the new Angular 21 @for loop.

Contextual variables give extra information about each item while looping — such as index, total count, whether the item is first or last, and even/odd row styling. These variables are extremely powerful for UI list rendering, tables, menus, and dashboards.

We also cover multiple practical examples + interview questions.
