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.

It would allow us to use numbers which is larger than MAX_SAFE_INTEGER.

At the moment using BigInt in "Mustache" syntax just throw error.
Sure, backu

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.

Even though --max-old-space-size is a V8 flag, I would expect us to document it, given that itβs probably the most useful V8 flag for Node.js users overall.

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.
This is about AvlTree.js - rotateLeftLeft, rotateRightRight method
rotateLeftLeft should be call 'caseLeftLeft' or 'rotateRightRight'.
Because base on the image on avi tree readme.md, rotateLeftLeft method is a right-right rotation.

Bug report
Looking at this,
https://github.com/expressjs/express/blob/master/lib/request.js#L79
It seems like express checks referrer (with two "r"s) first, then referer next.
Is there a particular reason why the double-r is checked first?
It seems like single-r should be checked first because it's standard.
Another reason to check single-r first is because it's easier to spoof double

const customizer = console.log // returns undefined => merging is handled by `mergeAllWith`
// good

I am wondering how this is counted as best practice while obviously from the node official documentation it should
Some of the issues below are already mentioned in other tickets, but I have the feeling that a proper generic issue is due to give it visibility, as for now the current package is unusable for many users.
- The typescript package doesn't respect the tsconfig flags, and many of them are hardcoded inside the meteor/babel package.
I understand that meteor needs to control some compilation option
