Write an Asynchronous Function with async/await

before i study how to write async and await, can you point to a video maybe of the various problems that this would solve... thx

The await operator can make asynchronous code flows easier to understand. This is especially true for nested or conditional async operations. It works with ES2015 promises (in fact, with any thenable) out of the box, so it's not too difficult to integrate it into existing codebases.

How are you able to execute functions with await and async when these are not supported yet by Node, I checkout the git repo and run it but did't get this running, what did I miss ? BTW great course. Thanks.

Current Node versions (7.6 and above) do support asynchronous functions already! Check the Kangax compatibility table for detailed information.

Great tutorial! One question, which version of Node.js did you use and I believe this feature is yet to land in LTS version.

As of today, the most up-to-date LTS version is v6.10.3, which doesn't support async/await. The upcoming v8.0.0 version will add support once it ships.

Hi Marius,

I can't even run async.js, node is throwing SyntaxError: Unexpected identifier for fetch. I've installed node-fetch locally and globally:

npm install node-fetch --save

npm install --global node-fetch

respectively, but it's still throwing the error.

What am I missing? Do I need to do something with Babel, or does node handle that automatically? My node version is 7.2.1 and npm 3.10.10

Cheers,

Chris

Node v7.2.1 doesn't support async and await yet, you'll have to upgrade to at least v7.6, or better yet, v7.10.0 (the newest version as of today).

first of all: pretty cool lesson, well done,.. missing parts: stop/interrupt the async-calls on user interaction (e.g. click a stop button, or on route-change etc,..)

Great course, thanks! Which editor/editor-plugins are you using for this split view?

I'm using the native macOS capabilities: Do a long press on the green maximize button and drag the window to either side, then select another one — that's it!

Thatz cool tip. Thanks

What editor plugin are you using for the function hover tooltip showing a function returns a promise? 🤔

I use Visual Studio Code, which ships with this sort of tooling by default — no additional plugins required.

How do I run this locally?

Getting json from the response is asynchronous? Seems odd.
