So how does Angular do
dependency injection? So I'm gonna show you something
that you probably will never, ever need to actually use, but
It's good to know what's happening. So Angular is object,
right, that's created. All part of that angular.js file. And it has an ejector with
a method called annotate. And I'm going to pass it
my function search people. Actually, let's console.log this so
you can see it. So this feature inside of angular,
I can pass it a function, and let's see what I get. Wow look at that. It parsed the string. And created an array,
one for each parameter. The name of the parameters
that the function expects. So if you think about it,
if a function contains a certain name. That angular say hey, I know that name. I know that if I see that I
should create an object and pass that object in that
spot to that method. That means I could actually put it
wherever I wanted in the function and Angular JS's code would simply say, hey
there it is, and I'll pass it right there. I'll inject it, dependency injection. I'll pass this object that I create
to that spot in the function. And that's what happens here,
up in the controller. So, if I console.log the scope, you can see that this scope
object was created and passed to the controller function because
angular looked at the controller function, parsed out what its parameters were,
and realized hey, one of those is scope so
I'm going to create scope and inject it pass it to the function. This is extremely powerful. This means all you have to do is put
the name of the variable correctly, the name of the object correctly in
your function and you'll get it. Scope is a service that's a part
of the core angular modules, but there are others as well and they also can get past to your function
simply by putting them in the list. So this is an incredibly powerful feature,
and really saves us a lot of time, and
also makes our code more testable, more verifiable, more stable. And that's what I do in JS's
structure is doing for you.
