    It's hard to believe that the same company saying this is backing up angular…. Just saying.

    "Promises have been well supported for a number of years"
    According to Google Analytics, 25% of our users are still on Internet Explorer 🙁
    Even on Windows 10, Internet Explorer beats Edge…

    A lot of this is due to business requirements, I.E. the trend to have the frontend completely separate from the backend so that the backend is just API, so that the same API can be deployed cross platform. That led to the rise of things like React, which require twice as much code to do the same thing just because people went "Oh cool look how fast it renders! We must build everything in React now!", and enforces all these insane rules about one way data binding for the sake of the all mighty "convention". Then usually about 30-40 libraries on top of that to get you out of the hole that React creates. The issue is not momentJS lol. But what can you do? Most businesses are way to strapped for cash and time to be worried about optimizing to that level. If you're worried about minimizing your JS code base because it's over 1mb, it's either because there is some sort of technical limitation you're hitting due to it, or you're somehow completely out of other much more critical issues, which has never happened anywhere I've worked in 15 years.

    ad networks and other 3rd party scripts that deal with user data are BY FAR the biggest problem with web performance and destroy the user experience. I wish this topic was discussed more in public mediums such as twitter, etc. Chrome has been THE leader in advancing browser features and security and I hope they consider '3rd party scripts' as an important problem.

    Well if someone needs that much js. It's fine if you are making a business application. Where you treat the entire js is the application.

    Why not just let the programmer export the code that is not used. From Google dev console.

    Exceptions prove rules in languages. A ratio that makes a language a language. There are more exceptions to the rules in JavaScript than what are needed to make it a language.

    I think the Turkish government had the Saudi Consulate bugged, the iWatch theory is just an excuse. They must have some gruesome video (not just audio) evidence about Mr. Khashoggi's body being hacked to pieces, his skull and genital removed by the Saudi's autopsy surgeon with his bone saw.

    I just care about what the fire colored fox on Osmani's T-Shirt says. Undefined something something function?

    One thing I really dislike about these types of things, and other content google puts out recently, is stuff like "promises are well supported for a few years now"; yeah, if you're talking about evergreen. Almost all actual web-developers still need to support IE11. I mean sure, it'd be better to only include those polyfills on IE11, but this whole pretense that IE11 doesn't exist or doesn't still typically need to be supported is absurd.
