Basically the summary of the video is :
1) If you want that a method should be accessible or present in all objects in javascript (for ex: arrays, strings, functions,etc) then you can set your own method in the top level Object (because everything is an object in javascript) by using | Object.prototype.{method name} = function(){} | , after doing this you will have the access of your {method.name} from all objects for ex: every array that you declare, every string that you declare and so on.
2) But lets say if you want a certain method that should be accessible only on a certain object ( for example : (this is used in the video) you want a trueLength(){this method returns the true length of an array by trimming all the whitespaces} method to accessed on all String declarations , then you can be like | String.prototype.trueLength = function(){ code that does trimming and return length } | and this will be accessible on all strings .
3) this keyword in javascript refers to the current context of who is calling . matlab this boleto jisne bulaya . example: if you say | "hemant ".trueLength() | then how will the trueLength() method knows that on whom it have to perform . so we use this in the trueLength() function definition so it will automatically take the context of by whom the method is callled , boleto jisne bulaya uska kaam hoga.....

I never 'knew' what all happened underneath 'new'.
Mind blowing detailing explaiend.
Thank you Hitesh Sir for this amazing explanation of prototypes. Covers everything right from prototypical inheritance to defining own prototype methods for various objects.
I love how you teach everything starting from old coding practices to how it has been evolved today.
For anyone learning JavaScript from scratch and aiming to become a software developer, this is the go-to series!!
Hello mam can i ask you something?im pursing bsc it , after that can i get a job as fresher ik frontend in web development
This playlist is full of detailed information. It is better than alot of PAID courses out there.
Thank you Software Expert Hitesh Choudhary Sir!
I am an English major student pursuing MERN stack following my passion. You contents are so helpful to understand things in details and it's work behind the scene . Thank you so much. You are affecting many students like me. ❤

@@DashinDanishbro whats your update?
@@kalsotraaditya98 Done with frontend almost.
Ab muje chakkar ane laga hai😂
same yar
Mark my words, In coming years this video will be one of the reason of making this playlist best present JS playlist on RUclips.
-धन्यवाद हितेश
crystal and clear explanation of this context. this means ''jis ne v bulaya ho'. All thanks to Hitesh sir. 😊
Hi can I get Instagram-id
Sir, this is the first time I could understood about prototype. Thanks
@ 27:00 begins prototypal (inheritance)
!
At first I didn't understand what he was trying to explain about the prototype but then I rewatched the whole video. After that everything became crystal clear. This is the best explanation of a prototype you can ever imagine.
Best teaching style....jis ka mtlb this
The portion where we added custom function to all objects was really cool
this prototype video is really amazing i learn so so much from this video specially jis tarah se aap ne samjaya. muje bohot lambe time se prototype samaj nhi aarha tha specially "this" and "new" key word but finally....... finally me acche se samaj gya thank you so so much sir. ❤❤❤ sir aap ese hi video bnate rhe.
Just watched till the end now and I'm speechless and awe struck.
Nowhere on the planet I assume had anyone ever taught JS in this depth.
❤
All my topics about functional constructor , new keyword , constructor function, prototypal inheritance and this keyword are crystal clear now . Great video Sir No paid courses teaches like you in depth . Thank you so much sir ❤❤❤
Itna depth aaj tak kisi JavaScript course me nhi hai.
Akshay Saini ka course dekho
How easily you made me clear about new and this keyword with the prototype concept..... you really nailed it 🔥
Thank you @Hitesh Sir. ❤ esi tarah video aayenge aur aese js topic milte rahenge to js mai mastery sach mai krr jayenge.
For people who are coming from Kotlin or similar languages, prototype function is a extension function for existing classes
25:55 In the OOP 42 class (at the 26:00 mark), it was explained that whether or not you use return this, you still get the object.
0:00 intro
2:50 start
7:10 diagram
9:20 Function as object
13:00 this
20:50 new
23:00 Notes
27:00 prototype
38:00 Inheritance
42:00 modern syntax of inheritance
Anyone can help jab hum function ki jagah par Arrow function use karte hai toh score ki value undefined kyu batata hai ???
@@apatel176 brother arrow function me aap new keyword use nhi kar sakte basically constructor function nhi hn arrow func normal func se hi constructor func bnta hn thats why arrow func ye cheeze support nhi karta
guru ji pehle to maza aa rha tha ab sir dard hone lagata h . bhot complex hote ja rha hai but aap in the end easy kr dete hai,
Information rich and information heavy video, took a long to digest and understand, but after few replays.

Really nice session😃 much appreciated!
This lesson had one of the best explanations in the whole series, just went through it and tried to solve the goal of adding the trueLength method to String by myself, took some effort and some help from mdn docs but now I feel confident about prototypes, and adding custom method and properties to them. thanks a lot, Sir.
