How to add a class to a block when hovering over another?

Question

Angular

How to implement a hover of one block through a bunch of ng-mouseover and ng-class and assign a class to another?
I put ng-mouseover in block 1 and got stuck.
Here is an example.

<div ng-mouseover = 'inHover()' class='block1'>
<!--Какой-то контент-->
</div>
<div class='block2'>
<!--Какой-то контент-->
</div>

Answer 1

<div ng-mouseover = 'isHovered = true' class='block1'>
<!--Какой-то контент-->
</div>
<div class='block2' ng-class='{"hovered": isHovered}'>
<!--Какой-то контент-->
</div>

In a simple case - just like this.
