- The users of this style guide will probably expect that all of the rules that it prescribes will be enforced by eslint. However, this is not the case - there is a secret, non-documented segmentation where some rules are enforced and others are not, because they would be "too noisy on a legacy codebase". An example of a problematic rule like this is covered in issue #2020. I propose that all of

Given the immense popularity of Docker and the need to harden it different per platform (see ideas below) - we'd like to start writing a Docker best practices section.
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
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

This is a proposal to modify the use-isnan
rule.
Current rule setting:
use-isnan: "error"
Proposed rule setting:
["error", {"enforceForSwitchCase": true}]
The switch
statement internally uses the ===
comparison to match the expression's value to a case clause.
Therefore, it can never match _case NaN

Since a lot of the categories have many articles listed, it would be helpful to highlight the top 2-4 "must read" articles in each category, if appropriate.
I should figure out how to format this, and which ones I want to highlight.
If the document.domain property is set in the page, _has
module throws error "Access is denied" when try to check window's property for example 'hasOwnProperty'.
So I think it is better to change _has
module like below.
var hasOwnProperty = {}.hasOwnProperty;
module.exports = function(it, key){
try {
return hasOwnProperty.call(it, key);
} catch(e){
return

The documentation states that this is Glide's structure, but specifically mentions adding the track attribute. So if that's required, is the HTML class structure also required or is it just for example?
<div class="glide">

<ul class="glide__slides">
<li class="glide__slide">0</li>

I'm testing out madge on my TS RN codebase, and I'm surprised to see that it just magically works without specifying a tsconfig.
For example
yarn madge --circular --extensions ts,tsx ./
Although this is cool and exciting, it gives me pause because the documentation doesn't explain how this works. I read the source and followed the path through a series of external npm dependencies. Af

I am using JsBarcode to make a barcode scanner programming sheet for our application. Our barcode scanner adds some unusual Code128 symbols at the start to make sure that regular barcodes do not cause it to change its settings. For our scanner the programming codes are always in format: START B, FNC3, programming code, STOP.
Forcing Code128B is well documented, but inserting the FNC3 symbol (
