Is it better to use getcomponent with a string or type?
It is better to use GetComponent with a Type instead of a string for performance reasons. Sometimes you might not be able to get to the type however, for example when trying to access a C# script from Javascript. In that case you can simply access the component by name instead of type.
Why does getcomponent return a generic data type instead of class?
Just to provide some background: the reason the above works is that you have to specify the type when using GetComponent (). Without doing that the generic data type returned is Component and that's the base class without your custom functions.

Can GetComponent return null?
Many times we use the GetComponent method to grab a reference to a Component attached to a game object, usually the same game object to which our script is attached.

Why did Unity stop using JavaScript?
It's a proprietary language and it doesn't actually follow any concrete specification of standard JavaScript and is modified at will by the engine developers. > Because of this, the vast majority of JavaScript libraries you find will not work by default in Unity.
Does Unity work with C++?
Both Unity and UnrealEngine utilize C++ in their source code: Unity is partially written using C++ and C#, whereas Unreal Engine is written in C++ entirely. C++ is widely used to develop high-tier game engines and critical service applications where optimal resource utilization and performance are a priority.
What does Vector3 mean in C#?
Vector3(Single, Single, Single) Creates a vector whose elements have the specified values. Vector3(Vector2, Single) Creates a new Vector3 object from the specified Vector2 object and the specified value.
What is a Vector3 in programming?
Vector3 describes a vector in 3D space, typically usually used as a point in 3D space or the dimensions of a rectangular prism. Vector3 supports basic component-based arithmetic operators: sum, difference, product, and quotient.
What does Vector3 up do?

I have finished the Udemy course. I then checked the unity learning course. I still don't understand this. What does GetComponent<> do and what is the most basic item it controls? What is a beginner like me supposed to understand?

It cannot alone get references to components attached to GameObjects which you don't already have a reference to.
Joe-Censored
Joe gave a pretty good answer. I understand that I can call a function using getcomponant but then I was asking myself, why not just write a big script and make smaller ones call out all the time to get something I need? performance would be one problem.

Returns the component of Type type if the GameObject has one attached, null if it doesn't. Will also return disabled components.

Why is Unity so complex?
Also there is a reason why Unity has so complex relations with script's constructors: it's because every gameobject and other stuff Unity does (rendering, sound, etc) in terms of memory is driven by Unity itself and scripts memory management is done by the c# garbage collector.
Can another script be attached to a game object?
It also worth considerating that any other GameObject can have a AnotherScript attached to it (and maybe more than one instance actually).
Can Monobehaviour constructor be used in script?
If you look through documentation you'll see that MonoBehaviour constructor can present in script but it also has a lot of restrictions. For example, you cannot have any params in it. Also it's very convenient to have ability to set up component's parameters via inspector. It's especially useful when it's done by non-programmers because you don't have to change code to modify gameobject's behaviour.
