Build the future of the web with modern JavaScript (Google I/O ’18)

This presentation gives an overview of cutting-edge JavaScript development techniques to build modern web and Node.js apps. Discover which features to expect in Chrome and Node.js soon, how the V8 engine optimizes for them, and how to improve real-world performance and stability on the Web and in Node.js.

Much respect to presenters for listing all supported browsers each time and not just stating the obvious "All browsers except Edge"

[@crustysoda]

these are all cutting EDGE features :)

[@Hshjshshjsj72727]

@@crustysoda 😒

[@laurenz1337_]

So many new things coming to JS! I am excited.

[@stefenov]

I love how the extensive know-how of building browsers acquired from Internet Explorer is now properly propagated to Edge. I particularly like the lack of support of any modern JS features and the weird CSS bugs. Do you plan to add an experimental flag to Chrome to bring us the Internet Explorer experience we have all grown to love?

[@jasonleo]

lmao

[@SimonBuchanNz]

Edge 16 supports all ecma up to 2017 bar regexp /u and some edge cases of getter/setter methods according to kangax, and the number of APIs supported is in line with the current production releases of other browsers. Ecma 2018 would be nice, but it's a bit weird to call them out for it when only chrome is complete.

[@beno7176]

:) good one

[@stefenov]

I agree, I was too harsh

[@CompTutts]

Private properties in JavaScript. Oh my god! I can't believe I will be alive to see this.

[@justinmoonboards]

JavaScript has had private properties since the very beginning, via closures.

[@xerotolerant]

We're on the bleeding edge here folks. Readable regular expressions. Who'd have thought that would ever have happened.

[@provasks]

Very cool staffs are coming! amazing..

[@NeoChromer]

nice, finally I can multiply in JS!

[@UrzuaNicolas]

finally JavaScript will be the same both for the server and the browser!!!

[@Richard77724]

<a href="#" class="seekto" data-time="2160">36:00</a> that's a nice python feature javascript deserved

[@MultiLenoxxx]

JavaScript is the future woop

[@aliselcuk7005]

Build the future web but don't forget: Googlebot is using Chrome v41

[@intcreator]

I always use Babble to transpile code for Edge.

[@devnull-p1g]

I don't know which version of Node.js they are referencing but with Node.js 10.4.0 "BigInt" is supported: $ node > console.log(BigInt(1) + BigInt(2)) // 3n

[@teresakhurst2399]

Too Cool! Great Work

[@HobbiCoast]

Javascript is everywhere. #Gyanuniversity

[@davidsalleyezonme1283]

Google you inspiring me so much.

[@JeraldJamesCapao]

Coooool !

[@ninjitaru]

have a question about recommended to use babel -env to transpile to specific browser version say that i end up with two js file, one that support new js syntax natively (for latest supported browsers), one that transpiled the js what is a good way to determine which one to serve?? do i write both in my script tag?

Finally JS is getting lookbehind :D

[@SamujjalMajumder]

JS now has Perl style Regex Matchers

[@everythingisfine9988]

I don’t want to transpile my code, but some browsers are lagging behind the times 🐌

[@TufikChediak]

About classes, JS use a poor level classes structure, why not implement the current specification in ECMA 4th

[@flemminghansen7748]

Use the platform, I repeat, use the platform :)

[@terencecheung1374]

Yeah, 2019 there are no more edge/opera icons. Emm..

[@gahaha1234567]

JavaScript now is overtaking Python.

[@mika2666]

just now? naaaaaaa

[@ajaysihota2299]

And Java?.. I hope

[@zealousprogrammer4539]

He is right, JS will eventually [inevitably] overtake Python, one area really shines is ML, data science and similar fields but guess what? with TensorFlowjs and all the libraries being rewritten in Nodejs[JavaScript] since JS is naturally for most developers even novice ones I thing the future of programming is JavaScript.

[@Hshjshshjsj72727]

Not for Ai or any of that, data science etc

[@hrgwea]

Finally we'll have regex look-behinds... for christ's sake!!!

[@antoniopantano4255]

Finally Microsoft is doing a great job.

[@fahmiirfan6923]

Can we get statically typed in js ?

[@farrellraafi1301]

You can with TypeScript

[@farrellraafi1301]

You can with TypeScript

[@xmuta]

Fahmi Irfan - Typescript

[@xmuta]

Farrell Raafi - exactly

[@highcollector]

We know we can with TypeScript, but a native JS version is needed for various reasons; hopefully it'll be added soon

[@dancovrboski9135]

Ako neme vrtat na rabota vo geterym vo prilep javno hese ot kazam od gogel poradi predastvo

[@SwapnilMhaske1]

Woah... I just hate how all browsers ship things slowly.

[@DJalem]

I want to know JS but i am bad at solving logic problems 😑

[@gregorslana7723]

solving logic problems comes with time, just go start building a project, and learn as you go. Logic is not that important nowadays, since you can google basically every problem. More important is understaindg the technology that you are using

[@SashNone]

Yea... interlacing in 2018... quite modern....

[@ericmcgrath2514]

LOL @ Edge, just stop trying Microsoft. We've endured enough suffering with IE.

[@kaikai7702]

阿三这么多 怪不得bug这么多

[@tomsoir]

Why, the hell, `finally` word (in try-catch), but not 'done' as in promise...?

[@xerotolerant]

I think try catch finally is a common pattern C-style languages. I don't think it was ever intended to mirror 'all, reject, race and resolve'.

[@reaper84]

IE Support is as bad as it always has been. Pathetic.

[@elgeekcurioso5150]

I'm so tired of hearing people saying that async makes code cleaner... It is not! Is just that you are more used to it, you are so C-like biased that you can't even understand any other syntax.

[@teckyify]

Nothing we need whatsoever, only bad programmers always want more syntax. The only feature we needed were native module loading and tail recursion. I hope they dont make of Javascript such a Frankenstein language like C# with a new language feature like every 10 minutes.

[@crazieeez]

...defaultSettings is ugly syntax. Javascript is becoming Perl. Why not just use Perl then. Add async to Perl, and bam call pa programming language to kill javascript.
