Beginner Scripting : Get Component

 Another interesting bonus task this week, this one is all about GetComponent , which is a very common in coding but not many people knows its exact function . But this video does a great job at explaining it, Get Component is basically the plumbing that allows your script on an object to be able to access that objects other components. However , as said in the video , using GetComponent is very expensive in terms of processing power and should be used as little as possible and ideally at the start of the awake and start functions.
