      "@babel/preset-env",
      {
        "targets": {

https://stackoverflow.com/questions/42183155/is-it-safe-to-use-async-await-now 

So depending on what you think is acceptable it is either safe or not safe. Note the following:
    This question was originally asked on 2017, and we have come a long way so async/await is much more safe to use now.
    By 2019, most mobile devices already support async/await.
    Node 8 is released on May 2017 so it should be safe to use async/await on Node.js unless your Node.js servers are very outdated.

[2020-01-30] Svelte 3: Rethinking reactivity

https://svelte.dev/blog/svelte-3-rethinking-reactivity 

Svelte is a component framework β€” like React or Vue β€” but with an important difference. Traditional frameworks allow you to write declarative state-driven code, but there's a penalty: the browser must do extra work to convert those declarative structures into DOM operations, using techniques like
that eat into your frame budget and tax the garbage collector.
Instead, Svelte runs at build time, converting your components into highly efficient imperative code that surgically updates the DOM. As a result, you're able to write ambitious applications with excellent performance characteristics.

[2019-08-28] Flow vs Typescript /r/javascript [[flow]] [[js]]

Having used both (Flow for one very large project and TypeScript for a few less large projects) I am very much in the TypeScript camp now.

Firstly, DefinitelyTyped has vastly more library defs available than flow-typed, which matters a whole lot more than you might realize. It's pretty rare that `npm install @types/name-of-package` comes up empty.

Secondly, Flow feels slower and buggier; I use VS Code full-time and have found that TS reacts to code changes far more quickly and accurately than Flow (almost instantaneously across an entire project), and provides much more useful error messages (I lost count of the number of times I saw `merge_strict_job exception: Utils_js.Key_not_found("LeaderHeap")`, which I believe usually indicates a bug in Flow itself but is also completely useless and extremely difficult to debug). Of course I realize that TS and Code are both Microsoft products so it's not surprising that TS works better, but even in Atom with Nuclide I found that Flow was a bit slow to catch up to things, and still sometimes threw very cryptic errors.

Finally, TS has a pretty solid built-in compiler which tracks the official spec, and natively supports features like `async`/`await`.

To your original question, I'm currently working on a React-heavy project with TS and have found it to have excellent support. Flow works very well with React as well, which is to be expected since both come from Facebook. I think either would be a fine decision, but definitely feel TS has the edge in stability and speed.

[2019-09-01] npm vs. yarn - which one and why? : javascript

https://www.reddit.com/r/javascript/comments/ad6zoj/npm_vs_yarn_which_one_and_why/ 

npm has greatly improved since the original days of yarn. With lock files and better dependency tree management, I find very few reasons to use yarn nowadays.
I'd say use npm until you find a feature from yarn that requires you to switch. npm is included with every Node.js install.

JavaScript

JavaScript (or js) is the primary programming language interpreted by web browsers. That is, it runs on the client’s browser rather than on a backend server.
