What is view encapsulation in Angular?

View encapsulation in Angular is a mechanism that controls how styles are applied to components. It helps to isolate styles so that they don't affect other components.

Can you explain the different types of view encapsulation?

Sure! Angular provides three types of view encapsulation: Emulated, Native, and None. Emulated is the default, which simulates native behavior. Native uses the browser's native shadow DOM, and None means styles are global.

When should I use each type of view encapsulation?

Use Emulated for most cases to avoid style conflicts. Use Native if you need true encapsulation and are targeting browsers that support it. Use None for global styles or when you want to share styles across components.

Are there any performance implications with these encapsulation methods?

Yes, using Native encapsulation can have performance benefits due to the browser's optimized handling of shadow DOM. However, Emulated encapsulation may add some overhead due to style processing.
