Our app is not yet a BMI calculator, because it only has two sliders, but doesn't show the calculated BMI number. In this lesson we will learn how to export any stream from a child component and use it in the parent component, in order to display the BMI calculation on the DOM.
You added .remember() after .flatten() but there is no explanation for this step.
@Rado, actually, .remember() is really important, I followed up the video and the code just do not work. I took me quite a while to figure out I need
remember() in order to make the code run !!!
