Just spent 3 hours on a segfault bug that could have been prevented had I been diligently putting const where it should be. Shame on me. Never be too lazy for const-correctness ever ever ever...1

One of my least favourite parts of the world of programming is the "there's a usecase for everything" attitude. Like take this part of "You don't know Javascript" https://github.com/getify/...
> But var is still useful in that it communicates "this variable will be seen by a wider scope". Both declaration forms can be appropriate in any given part of a program, depending on the circumstances.
Now you would imagine that after this comment the author added a good example of this or at least had a reference to another part of the book where it showed this, but nope it goes on to include this note:
> It's very common to suggest that var should be avoided in favor of let (or const!), generally because of perceived confusion over how the scoping behavior of var has worked since the beginning of JS. I believe this to be overly restrictive advice and ultimately unhelpful. It's assuming you are unable to learn and use a feature properly in combination with other features. I believe you can and should learn any features available, and use them where appropriate!
Which again, "durr there's a usecase for this feature" or rather it's coming with basically an insult towards people who don't think you should use var without actually addressing anything. And what usually happens when someone tries to "there's a usecase for everything" is to either be really vague, or come up with some silly thing that you "might" do. -
Filthy Pollo: import {globalStore} from '../main.js'
Filthy Pollo: is that unstandard javascript?
Filthy Pollo: it makes me think it's from webpack
Filthy Pollo: unforgiving...
Ron Chi: i wont answer these questions again
Ron Chi: i already told u chrome supports imports its been a few months
Ron Chi: modules are evaled once, so if u have some state living in ur module if u reimport it ull just get that same state
Ron Chi: myModule.js - const myShit = { 'a': 'eh?' }; export { myShit };
Filthy Pollo: https://i.imgur.com/1X4Taik.png
Filthy Pollo: gg
Ron Chi: index.js - import { myShit } from './myModule.js'
Filthy Pollo: import and export are unexcepted token
Ron Chi: import needs to be used at the top of a file, before any other code
Filthy Pollo: https://i.imgur.com/myrrIMx.png
Filthy Pollo: Im going to assume import and export aren't supported in the browser
Ron Chi: because ur squigly line in ur editor?
Filthy Pollo: This feature is only implemented natively in Safari and Chrome at this time. It is implemented in many transpilers, such as the Traceur Compiler, Babel or Rollup.
Ron Chi: https://github.com/paulirish/...
Ron Chi: actually i dont think its handled properly by babel, webpack handles it
Filthy Pollo: what the fuck why use import and export that wont work in other browsers like firefox, edge, etc. ?
Ron Chi: because other browsers are slow
Ron Chi: its still standard
Filthy Pollo: your answer is not really professional
Ron Chi: ?
Ron Chi: why because its my fault that other browsers are still working on it
Ron Chi: they fought over implementation details forever, than it has to be implemented properly before shipping it
Filthy Pollo: Im blaming the people who are still using export and import in the browsers
Ron Chi: u wont be using modules without transpiling without some limited market for a couple years, otherwise ull still be using rollup / system.js / webpack
Filthy Pollo: obviously webpack
Ron Chi: thats up to you, it seems the google ppl use rollup
Ron Chi: but most of the community chose webpack
Ron Chi: angular 2 uses system.js internally i think
Filthy Pollo: Firefox 54 – behind the dom.moduleScripts.enabled setting in about:config.
Edge 15 – behind the Experimental JavaScript Features setting in about:flags.
Filthy Pollo: nobody wants to be bothered to change settings in flags
Filthy Pollo: the developers who use experimental features are weirdos as hell
Filthy Pollo: the joke is when they use experimental feature for production and force them to download chrome
Filthy Pollo: Monopoly as hell
Filthy Pollo: Corruption of User Experience
