I noticed, when reviewing freeCodeCamp/freeCodeCamp#38016, that a lot of HTML was necessary to create challenges that looked good (freeCodeCamp/freeCodeCamp@7b9db26#diff-8d5114b548781516c78ac91bc507f8ebR14, for instance). While using HT

What problem does this feature solve?

I just spent way too long debugging something really weird until I realized I accidentally wrote :v-if instead of v-if.

A warning when wrongly using shorthands like : on "native" vue attributes could prevent this bad experience easily.

What does the proposed API look like?

:v-if="foo"

--> console.warn("You specified v-bind:/ v-on:

This is a continuation of an previous issue to add support for the BigInt data type in React DevTools.

Original PR facebook/react#17233 (merged)

This happens when you try to copy a BigInt value to clipboard via React DevTools.

Would @nutboltu mind taking a look?

backend.js:1 Uncaught TypeErr

The docs for the vertically centered don't appear to fully match what should be shown. The "Launch Demo Modal" text should be "Vertically centered modal," but what really matters is that there's no class mentioned for modal-dialog-scrollable in the Vertically Centered section.

The current Airbnb config has the "import/extensions" ESLint rule turned on. However, the reasoning for this is not given on the official style guide, and even the fact that the rule is turned on at all is not documented on the style guide. For example, there should be a blurb added to the section on modules that says something along the l

Huge and nice collection and also getting very much appreciated from the community.
It would be great if somebody can translate into English then it will be reaching out to global.

I think it makes more sense to return an empty array

// invalid input return null or throw an error
if (!setA || !setB) {
    return null;
}
if (!setA.length || !setB.length) {
    return []; 
}
// or do nothing since the for loop will not trigger anyway

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 );

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

I would suggest for the sorting examples some name changes that make it clearer what is going on.

cmp -> comparator or cmp

desc -> descendingComparator or descCmp

getSorting -> getComparator or getCmp

K -> Key? or KeyType? I'm not sure what this should be called because I haven't l

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.

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 :.)
