- [Instructor] Now that we know what to use…and what not to use in (mumbles) scope…let's see how scope inheritance work.…We noticed before that the variable force…is somehow inherited from the internal control.…I'm going to do one last experiment…before I explain exactly how the scope inheritance work.…I'm going to add another input field…in the internal control (mumbles)…and bind it, also, to the force.…So, let's add another input field here.…
Type number.…And let the ng model of it be, again, force.…We would expect this variable force here…in the input field will be bound…to the same force variable here, here, and here.…Let's see what happens.…Notice what happens when we change the force variable…from the input field in the playground control.…As we expect, whenever we change the field…the four values change as well.…
The value here, here, and here.…Let's see what happens if we click the reset button.…Again, all the values have changed.…Now, let's try to change the force variable…from the internal control and see what happens.…
