5 MUST KNOW JavaScript Object Functions

In today's video I'll take you through my top 5 MUST KNOW JavaScript object functions.

These functions can be used for a wide range of things such as array manipulation, parsing, copying data, moving data and controlling the way developers interact with your code.

For your reference, check this out:

There is always something new to learn from Dom as far as JS is concerned.

Иногда без понимания английского языка можно понять суть из примеров и их результатов. Здесь, как и в некоторых (редких) Dom's videos, не всё ясно из контекста изображения. Тем не менее, я рад, что вижу такой огромный набор видео от этого человека! Я - программист, но в другой области. И мне интересно изучить и другие стороны разработки. Я рассматривал курсы, но их предложения не вызывают у меня желания заплатить иди даже рассматривать их безоплатно (for free).
Я иногда читаю комментарии на этом канале, и я вижу, что я не один такой, кто смотрит Dom's videos, but not clearly understand speech in English 😄
Это означает, что именно этот человек является отличным преподавателем даже для зарубежной неанглоязычных зрителей.
Thank thou, Dom! Thou is the best my teacher!
P. S.: Some words I gave in English because it may be not clearly translated from Russian by many popular translators (including humans).

Great video! The clear audio, % of screen real estate used, & the face-to-face visual instead of a classic "voiceover" typically added in post go a long way in making this a compelling tutorial.

[amysheeter]

thank you for your time and knowledge.

[eidenblock]

thank u very much for your work.
Very simple and understandable explanation

[SandeepKumar-zbuf]

Good work my elder brother, learned a lot from your video today.

[sahiraahamed]

Thanks a lottt sir.. For new knowledge..

Brilliant vid as usual.

I will say I'd be much more likely to rewatch these/bookmark these/refer to them in the future, if this was five separate vids, each titled by the method which it teaches. Then you could have playlists for meta-topics like "JS Array methods", etc.

Just a thought.

Keep up the good work man!

What’s good about your tutorial is the practical use case when u explain the code

[bozidarbralic]

I literally adore your content and have learned a ton from you, that being said. Maybe it wouldn't be bad to tell people that Object.freeze and copying an object with spread operator creates shallow copies and why should they be aware of that.

Greetings boss
I love all your videos and it has helped me a lot
Please can you do a video on how to add the print option on your webpage
Thanks

Thanks for sharing these 5 JS object functions, Dom. [Q] - Is there a way to throw an error when modifying frozen objects?

[montebont]

Let me begin with a big "thank you" for all your tutorials. I started programming in the late 1970's (Z80 and IBM 370 assembly and later C).
These days it 99% javascript and a little bit of PHP for the server.

Question: why do you use the object.assign(<object-name>, ...) syntax? What wrong with <object -name>.assign(...)?

I've seen this syntax even on object literals: const x = {name: "Ed", age: "none of your business"}.freeze();
Perfect (and IMHO mandatory) for all sorts of lookup tables.

Is it just coding style or is there a good reason for your approach? I searched MDN but no luck.

Anyway...thanks again and keep up the good works...

One thing that has puzzled me about JS is why they sometimes implement function as class methods instead of putting them in the prototype. For example why not person. assign() and person.freeze().? After all, you can say stringVar.toLowerCase() etc,

Hi, is there a way I can get my youtube channel analytics through Youtube API. Just say I want to see which of my videos got how much subscribers, or I want to get URL of my each video, or live actual subs count(isn't seen publically). Is there a way?

[antwarior]

so is any of this stuff useful beyond the console? how would someone use this in an application, its time to get away from showing how to console everything and show how to use things in real applications

[xenocampanoli]

I would never ever use any of these if I could possibly help it.

[nordthur]

Please, do not use "right here" and "here" that often
