JavaScript Beginners Tutorial 25 | OOP | Abstraction with example

An abstraction is a way of hiding the implementation details and showing only the functionality to the users
Abstraction hides certain details and only show the essential features of the object.
This approach improves understandability as well as maintainability of the code.

Very helpful Raghav, thank you for posting. The microwave example was a clear, common example and your coding walk-through was thorough, and nicely paced. Your final analysis of HOW this abstraction is helpful in changing only code in one (or a few spots) and not having the user care about those changes was particularly helpful.

[mashooraraf]

Best explanation I ever need in this topic. Thank you very much.💚

[murielarnio]

I very much appreciate this. Thank you very much for having this. It's very helpful.

[rekaviles]

That was extremely helpful, thank you. Also, I have that very microwave that you used in your example. :D

[AnthonyOdama]

This is very helpful, easy to understand, very easy to follow, thank you Raghav

[mohanbalasubramani]

Perfect explanation...appreciate it...thanks

[satdiver]

Thank you for keeping it nice and simple :)

Its not a abstraction. It is a encapsulation example. This information will cause confusion in people, please update it.

[ShaileshKumar-smns]

Playlist done - great refresher ... Looking forward to Es6 topics if you can pls..

[saurabhtapkir]

The way you explain thats too easy man 👍😁

[soubhagyajigautam]

You give provide the link of the playlist in the description or you can also share the link of your your previous related video

[janyam]

what about closures, callbacks, modules and all? I was really hoping you would have made those videos too

[stevengaona]

Can you explain this from the user perspective? Who is the user here? And in what way would they be trying to access the internal data? Would they be making changes from the UI or will they be opening up the code and making changes? Im not understanding that. Who are we hiding this data from?

This is not abstraction. This is encapsulation. Abstraction is implementation details hiding

Hello Raghav, declared JS constructor as function . What is the advantage of declaring employee as function instead of constructor. Can't we achieve with constructor the same. Thank you.

[hileooo]

HI Raghav, thank you for the videos.. will these cover all the JS concepts.. please advise..

[madhavikatta]

This was extremely helpful sir
But where can get practice questions in your website . I didn't found the practice questions.
Plz reply sir.
I am requesting you

[antonarbus]

Thanks for the video. Can anybody explain please why abstraction is explained with constructor function, instead of class like in previous videos about encapsulation, inheritance & polymorphism? Can we 'hide' properties via class in JavaScript? I tried to use #private properties in class, but they are still visible in dev tools inside instantiated objects. Hope my question makes sense.

what font-family are you using in VSCODE ?

This is not Abstraction. This is Encapsulation.
