Chapter 1: Shaping docuements with Project:
An example was given where “gravity” is assigned the value of gravity.value but it was explained in the video that we were “RE-ASSIGNING” the value of “gravity” so does this mean that we changed the structure of the entire db so that gravity no longer equaled gravity.value? Did this $project operator demolish gravity.value forever? Or did the video not explain that a new field name was being created as “gravity?” I’m confused. Was the value of gravity re-assigned temporarily or was it permanent? What is the end result to the embedded value named gravity.value?
