JavaScript
JavaScript (JS) is a lightweight interpreted or JIT-compiled programming language with first-class functions. While it is most well-known as the scripting language for Web pages, many non-browser environments also use it, such as Node.js, Apache CouchDB and Adobe Acrobat. JavaScript is a prototype-based, multi-paradigm, dynamic language, supporting object-oriented, imperative, and declarative (e.g. functional programming) styles.

Feature request from a DevTools user at Faceook:
If I mouse over a node in the flame graph if you can highlight it in the view like the inspector that would be really amazing!
Chapter in question: https://github.com/getify/You-Dont-Know-JS/blob/master/es6%20%26%20beyond/ch2.md#template-literals
The suggestion seems to be that the template literals would be all about strings; there's only examples that result in strings, and phrases like "final string value" and "generating the string from the literal" are used in what should be a general context, but the tag function
The max-classes-per-file rule is enabled in rules/best-practices.js but there is no mention of this requirement in the docs. If this is a best practice, I'd like to know why.

Suggested Improvement
The current implementation of
test-source-map fails on Windows 10. Looking at the test file, there is a special case for Windows that is not being met under certain conditions. I believe it has to do with how git is configured to handle line endings on checkout but I still need to confirm

The deprecated decodeDracoFile method should be removed and replaced with a parse method similar to other loaders. Currently decodeDracoFile does not propagate errors, and should do so. So probably a signature like:
dracoLoader.parse( arrayBuffer, /* options, maybe? */, onLoad, onError );Search Terms
- return type quick fix
- async function quick fix
- global promise type
Suggestion
It would be nice if TypeScript contributed a quick fix to resolve The return type of an async or global function must be the global Promise<T> type errors. The fix would simply wrap the existing return type into a Promise.
Checklist
My suggestion meets these guidelines:
Please file any Docs or angular.io issues at: https://github.com/angular/angular/issues/new/choose
For the time being, we keep Angular AIO issues in a separate repository.
Description
So our function arrayToHtmlList is in a pretty bad space and could use an update. We already had some discussion over at #675 but I wanted to move the update discussion over to an issue for more visibility.
Current problem:
It uses an awkward query selector instead of the `document.prototype.getElementBy
In the Swipable Drawer API documentation, more clarity could be added to how to utilise SwipeAreaProps on the Swipe Area. Maybe add a brief example. I couldn't find any sandbox examples of it being used.
In the mean time, does anybody have examples of where this feature is used? Or how I might use it? Can it be used for Styling it? Maybe
Bug report
If you follow the readme procedure, the following error will occur in the first npm install express.
saveError ENOENT: no such file or directory, open '/xxx/xxx/package.json'
As you know, the cause is package.json does not exist.
Other users seem to have a similar error, so it seems better to add npm init to the readme.
Or I thought it would be nice to bring a link `Please follow

Hi, I have been spending quite sometime wondering why a simple dropdown was not working.
Is not specified on the docs that the must have the class 'dropdown-trigger' (any other is not triggering the dropdown!)
Just a matter of documentation but crucial in order not to waste time :.)
example, this will not work:
<a class='dropdown-button-example btn' href='#' data-target='dropdo
