Nice. Definitely important functions to understand. My understanding of how prototypal “inheritance” works is that call is used when an object calls function from further up the chain, does that sound about right?
I guess what I am getting it as if you had an array called xs and you called map on that array, would you in effect be calling Array.prototype.map.call(xs,function)? Since map doesn’t belong to xs. I know I am being very specific here 😃

I would say the method is
called when you are not adjacent or you are detached from the method you arecalling.callserves an extremely important purpose of running a method under a context you provide.This means that we can call any function, explicitly specifying the reference that
thisshould reference in the calling function.I guess what I am getting it as if you had an array called xs and you called map on that array, would you in effect be calling Array.prototype.map.call(xs,function)? Since map doesn’t belong to xs. I know I am being very specific here 😃
