Mutability vs Immutability in JavaScript

Underrated channel

Great explanation.

i rarly comment but you are great sir keep it on

Well explained

Great video! Subscribed!

I am amazed at the beauty and clarity of the explanation. Thank you very much , keep going

wow this is so simple to follow! thanks

Cleared my concept in 7mins instead of reading 100's of lines...thanks

Like & suscribe

Great Video .. Good works

Maraming salamat po

Really awesome.

The author showed the wrong example of string's immutability. It only shows that STRING are PRIMITIVE type, but it is not about immutability.
Example of string immutability:

const str = "Hello"
str[0] = "B"
console.log(str); // Hello

Nice content !! Thanks.

Thank You For Your Great Explaination

Thank You Sir!

BEST EXPLANATION⚡️🙌🏻

You do a big mistake. Array and Function are Object. They are a subtype of Object

fantastic

Making a change to either Variable representing the person Object doesn't change 'person1' and 'person2' at the same time - It changes ONCE what both Variables are referencing. This is a HYPER important distinction. It's not going through 100,000 objects and changing their values 100,000 times it's just changing the value 1 time that 100,000 objects are pointing to.
ALSO
It would be a good time to explain how to CLONE an object so that you CAN treat them as two separate entities if you so desire.

AND
Objects, Arrays and Functions...Really? Arrays and Functions ARE Objects (in JavaScript); thus strictly speaking there is really ONLY ONE Reference type, Objects with Arrays and Functions being a subset of Objects (as are Dates, Math Objects and Regular Expressions too - but these are tied to the compiler as a special type of 'constant' thus they can't be corrupted).

awesome

good work keep going 👏👏👏

I've heard a lot about concepts like "primitive & reference" types and "mutability & immutability" in JS but never understand them thoroughly until now. Your way of explanation is simple and understandable. Thank you for sharing!

Thanks for giving such a clear explanation !! This video is really helpful for developers in identifying errors caused by mutability.

Such a great explanation bro! thanks a bunch.

Very Very Well Explained
Thank you Soo much Dear

Thanks so much!

thank you, great explanation !!

This is a good beginner's introduction. Well done video!
More info: cloning / copying objects and arrays really has no shortcut in JS. Properties that are objects will still be referenced, not copied. And since objects can have circular references, even writing an algorithm to handle it is non-trivial.
(Then there's the really weird stuff like proxies, non-enumerated keys, copying the prototype chain, etc.)

Thanks, my friend. I am learning functional programming and this immutability concept has been very hard to get used to. Your video helped me a lot!

Wow thanks for the video, it helped me so much! :D

What an under-watched channel, I didn't expect much because of the low view count (470?!), but this is of the same quality as much larger channels, I think you will blow up soon just keep making videos of this quality.

Drop the fake accent

Great explanation

This is a great video and really solidified my understanding of this concept. Please keep producing these videos they are excellent. Thanks so much!
