inheritance in JS => When an object trying to access variables and properties of another object prototype is an Object that get attach to function/method/object and this object has some hidden properties Whenever we create object/ function/ methods/ array/ variable , these all are attached with some hidden properties, which we call prototype __proto__ is reference to prototype ( or it points towards prototype ), if we want to access prototype, we do __proto__ prototype object has a prototype of its own, and so on until an object is reached with null as its prototype, this is called prototype chaining

Thanks for summarizing buddy

@porobertdev 6 ай бұрын

Just wanna point out that the __proto__ is an old method. There's a new method (somewhat inconvenient if you ask me): Object.getPrototypeOf(obj). Learned from TheOdinProject 🙂

@astroflexx82 2 ай бұрын

Don't use __proto__ to access an object prototype, use Object.getPrototypeOf() instead.

awesome explanation. First, I used to read on MDN then refer to any video/blogs/articles for a simpler and short explanation. Now firstly I'll watch your video then refer any other study material. Please never stop making such great videos.

Awesome video Akshay! Just a side note that strings,arrays all get coerced into its object equivalent called as wrapper object when we try to access the built in properties. This is the reason why we use the dot(.) Operator to access them.

If not the best content out there on prototypal inheritance, it surely bridged the knowledge gap between __proto__ and prototype. Thanks Akshay for the video. keep up the good work. Quick tip: __proto__ is on the object instance, prototype is on the constructor function.

Yesterday I wasted my 3-4 hours on this topic with some videos on KZfaq. However, I did not fully understand the subject, there was always a missing piece. I could implement but this was just usage without understanding fully. Now, in 20 minutes, the subject has become completely clear in my head without any doubt. There is a serious amount of information pollution on the Internet. You really did a great job Akshay. I will be watching all your javascript-related videos for the next 2-3 days. Thank you so much for good and precise information.

Hey Akshay, wonderful lesson. Thanks a lot for making it so simple.Your videos make JS easy and hence more interesting,as they say ''once you understand you get interested" .I would appreciate if you could come up with a video on DOM Manipulation without using Jquery. I know there are many resources available for this on the web but a video from your end will definitely clear the things in a much much better way.Hope to get a solid foundation video on DOM maipulation with Vanilla Javascript. Thanks in advance. :)
