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 problem does this feature solve?
It would allow us to use numbers which is larger than MAX_SAFE_INTEGER.
What does the proposed API look like?
In HTML, {{BigInt("100")}}, {{100n}}, {{2n * 50n}} or {{50n + 50n}} should show "100" (it can be just simply string by using .toString()) at frontend.
At the moment using BigInt in "Mustache" syntax just throw error.
Sure, backu
When option "Highlight updates when components render" is activated the whole page repaints in rapid succession after the components state has been changed. It causes 100% CPU usage by the browser and unpleasant DX due low fps.

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.

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.
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 );TypeScript Version: 3.7.5 and 3.8 (91ffa1c752ac26882b1426fb4c9012701c1d908e)

One of the more significant complaints I've seen is the confusion caused by all the individual repositories being so spread out across three different github organizations. While there are conversations happening about how those repos should be organized, one interim step is to provide a roadmap that outlines all of the relevant repositories, where they live, and how they relate to one another. Th
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.
