What is Exported Directive Context in angular?

Question

I'm new to angular, while learning angular from it's offical docs I didn't get what is a directive context and a exported directive context.

Can anyone please help me out what is it and how it works... Thank you in advance.

"Context" in this case refer to the variables that a directive can access to. For example, ngFor, you have index, first, last -> that's the context defined within the directive and they're "exported" for you to use. — Jimmy, Nov 20 '22 at 13:00
Is that mean a directive internally manages a bunch of variables in his context and some of them are exported out to our use... — Jay Bansod, Nov 20 '22 at 13:57
yes, you can say that, the ngFor let you use first, last and those variables/internal state is reflected by your input/express (ngFor="let a of X" - first/last depends on X) — Jimmy, Nov 20 '22 at 14:00

The official docs shows good what a directive is and how you can using it. Here is a Stackblitz example how a directive works.

And here is the guideline.

With a directive you have access to its element. Examples are available on the official docs (see link), too.
