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.

What is the current behavior?
In current behaviour, I can create a functional component that starts with lowercase and I can use it by importing it with the uppercase name. But if I s
As we’re using the same navbar across all our projects now—docs, icons, and blog—I’m wondering if we should be linking to our GitHub org profile instead of the Bootstrap (or Icons) projects in the main navbar.
Thoughts @XhmikosR, @MartijnCuppens, @ysds, @Johann-S?
In What about &&? section we have the following code.
function foo() {
console.log( a );
}
var a = 42;
a && foo(); // 42
result in comment should indicate that foo was called. but in fact we would get same result of "42" if first operand had been called (like in || operator). i think results of a and foo() should be different to make the example be clearer.
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.
Consider the following snippet run in the main process where one wants to listen for "will-prevent-default" events and after some asynchronous operation (do_something, a call which returns a Promise) initiated by the event listener, depending on the result (result) of the operation, call preventDefault on the even

Suggested Improvement
There is a request to remove axios.all and axios.spread (axios/axios#1042)
Although the functionality has not yet been removed, we can at least stop advertising it if there is intent (with good reason) to remove it. We can still keep
When not using a file extension in ESM - eg import pkg from './path' we currently just throw a straightforward not found error. As proposed by @MylesBorins in nodejs/modules#443 it would be useful to enhance this error message.
Ideally the error message should run the CJS resolver and say "the CJS resolver would have resolved this module to ...". We actually previous
Huge and nice collection and also getting very much appreciated from the community.

Redundant condition
This condition is redundant, the while condition covers the case where n equals 1.
p.s- I will exploit this opportunity to say thank you for this repository.
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 );📚 Docs or angular.io bug report

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
Hello!
According to the documentation the verbose preset should "Output everything" in stats.json file. However, in the source code the modules property is set to false for the verbose preset. Therefore, it's not outputting "everything".

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
I want to use Chart.js in IE9 but now it only supports IE 11+.
I remembered that the old versions (i.e. 2.5.0) supports IE 9+, but the links always pointed to the latest documentation. So where can I find documentation for historical versions?
I searched the issues but did not get an answer. Thanks.

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
