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

In twbs/bootstrap#30414 we discovered the skip links do not look that well if backported to v4:

We could also improve the theming in v5, in some viewports, it also covers a critical part of the navbar
 {
return null;
}
if (!setA.length || !setB.length) {
return [];

https://material-ui.com/components/menus/#simple-menu states:
Simple menus open over the anchor element by default (this option can be changed via props).
How can this be changed via props? The page doesn't say. I went to the Menu API page, and I don't see anything simple like open: 'below', or an offset.
Developers have been struggling to figu

Bug report
Documentation Is:
- Missing or needed
- Confusing
- Not Sure?
Please Explain in Detail...
I needed to produce a number of charts with a consistent yAxes logarithmic scale so that users can compare between charts.
I tried setting the same yAxes config settings for each chart:
beginAtZero: true

Express uses hardcoded values for debug namespace, for example:
https://github.com/expressjs/express/blob/b69b7605b07b41273acc931d25ab585377bcd107/lib/router/index.js#L20
and it is extremly hard to determine in output where things are happening while doing TDD on microservices architecture. It would be nice to allow to specify prefix for namespace, i.e. per microservice which is an express app.

const customizer = console.log // returns undefined => merging is handled by `mergeAllWith`
// good
mergeAll([{ a: 1 }, { b: 2 }]) // { a: 1, b: 2 }
mergeAllWith(customizer, [{ a: 1 }, { b: 2 }]) // { a: 1, b: 2 }
// A-OK; customizer logs the following:

You're welcome to contribute ideas and write best practices - writing and brainstorming will people is an amazing way to deepen your Docker understanding.
At first, we want to collect ideas for best practices, solidify a list
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

Was checking babel/babel#11478 and testing out syntax and noticed we don't error with the normal "use this plugin/preset" like we do for proposals with JSX itself. @nicolo-ribaudo mentioned it's probably since jsx is implemented as a normal plugin so we didn't have `this.expectPlugin("recordAndT
Hi,
I'm looking for something like .prettierignore but on a global level, i don't want to copy that file to every new directory i make just to ignore 1 file extension which isn't supported anyway.
AFAIK this isn't supported right?
BTW the extension in this case is EJS which prettier thinks is JS and some other stuff so the best way really is to ignore .ejs as a whole.
