Could you please clarify the distinction between two variables a1 and a2:
app.controller("someCtrl",function(){
this.a1=somevalue;
var a2=somevalue;
});
Also, can you explain the lifespan of variable a2?

Both variables have the same lifespan, but there is a key difference between them. Variable a1 has model bindings, which are crucial in angular applications for accessing the variable in your view. On the other hand, variable a2 does not have model bindings and cannot be accessed using $scope within the view.
Put simply, when you use this.a1, you are essentially adding a property named a1 to the object that is referenced by this at the time the controller function is called. As you are calling the constructor function, this points to the controller itself, allowing you to utilize a1 for data-binding purposes. On the other hand, declaring var a2 will create a local variable known as a2 within the function.
