JavaScript ES2020 awesome new features. 

I've been waiting for these to make their way from TS into JS for so long. Great stuff!

Thanks. Another great video. Happy New Year!

Great work TechSith. You're one of the best technical teachers on RU-vid and trust me, I've watched too many videos on JS. Keep up your good videos. I like that you give examples to put this into context.

I've just finished this big playlist of Advanced JavaScript Topics. I've learnt a lot. Thank you for the great content!

Cool video😍 at start of the year 😊 Keep rocking

Cool video. Happy New Year!

Perfect!. Thanks for the video

great stuff

Thanks! I love this channel. When I started learning JS I was also learning TS so I used the "?" operator in TypeScript, but I thought it was JS, it was disappointing for me to realize that it was available only on TS. Thanks Hemil!

Great sir Thank u

Great!

Thank's

Thank You so much for the video Sir

Thanks, it will help us to write clean code

Very nice

Thanks

its awsome

Definitely a decent way to start the new year 2020 with ES2020! Thank you sooooo much for this sharing. ^___^b

I like how they have borrowed ?? and ?. from angular. It makes coding thing with vanilla js much more simpler. This can make pairing ?. with ??. Oh my... Happy New Year techsith

Happy new year #techsith sir

BigInt, globalthis, allsatelled are 2019 features. ?. I m using this feature since 2018 in angular. ?? is new for me🤘🏻🤘🏻

We really like the way you're teaching. We started teaching project-based React. And would appreciate your feedback.

Should have called the 3rd promise p4 just to trigger everyone's OCD.

Excellent video. What software do you use for video editing?

Thanks for the video ! Can you please also guide us over data structure and algorithms in Javascript? Would be a great help

thanks for the video. why optional chaining still not working in react or angular app? they use webpack & compile es6 to es5 using babel-loader only angular template supports it.

Hi sir. What are the steps we should follow for migrating a project of es6 to es2020. Could you please provide any best resourse or anything.

Mate, as for the " ?. " operator Doesn't it already exist in Typescript? I remember having needed to use it quite a few times back when i played with Angular in the past I dunno why i always believed that it also existed in Javascript ;D

Does the ?? Comes with all version of react as they have inbuilt babel?

How different it is from ES2019 and ES6? Is it required to learn from Test Automation (with JavaScript) perspective? Please confirm.

Hi Sir, how can we know latest updates or docs from related to ES. Like ES6 or ES7 or ES2020 features and all. I tried MDN but its showing all things. Where can we find these latest ones?

can someone explain to me why console.log(x && x.profile && x.profile.name) doesn't return false when they are not defined shouldn't this expression be transformed in a boolean when using &&?

The best feature i liked is x?.profile?.name ..

how to download embedded pdf from js viewer from website ctrl+p not working, display : none to display : inline not working any other way to download. please help me

x?.profile?.name was basically available in ES2018 too

Sir any tutorials on Blazor?

When i can use this without babel?

He didn't say that the upcoming year would be good, how did he know?

all these cool new features. Too bad we still have to cater to people using IE.

WHY OH WHY OH WHY did they make the spec to be "fulfilled" instead of "resolved"? Why introduce inconsistencies in the terminology that has been used for 5 years already! I just don't get it. Fulfilled is also a word easier to miss typos in.

Would be great to make some updated and COMPLETE and opinioted development setups for 1) Component library development and 2) For application development WITHOUT frameworks. Like... VS Code settings.json, node, yarn, lerna, typescript, eslint, prettier, husky, lint-staged, mby hygen, git, npm. While there are a ton of material on how to use those tools in separation, firstly 99,9% of those tutorials are real crap and far from real-world development. Secondly, often there are tweaks and tricks to compose different tools to play together nicely. Think of .gitignore and lintstagedrc. Or tsconfig 'extends' property for better monorepo code organization for different builds. Or... i often see tslint and eslint in same repository which is somewhat outdated thing to do. Typescript component library monorepo setup. How to do that? Rarely who knows that. How to configure eslint with prettier? Rarely who exposes good practices. "You can do this or you can do that" is bad way to teach something. You need to teach about caveats, tricks, USECASES when to prefer one setting over another. It would be much better to have OPINIONATED, but complete setups than non-opinionated, but incomplete setups. And... in my experience there are those 2 kind of setups mostly used. One for NPM library development and another for application development where you import your own NPM modules.

You can this condition:- if('name' in x.profile) till '??' is not available
