Highly Experimental

If you are using this already, consider changes soon due the discussion around current ESX proposal.

Feel free to keep an eye on udomsay as that will be the implementation reference for consumers.

user-package-stats

I was poking around trying to figure out all the packages I have access to publish and got curious. So I write this little script to determine the download stats for all the packages I have publish access to.

Feel free to try it yourself. Just change the username passed to getUserDownloadStats.

By default, the stats are sorted by their average daily downloads (descending). That should give you an idea of the most "popular" package of a given user relative to how long that package has been around.

You can use it with npx like so:

bnb

defaults:

• npm config set init-author-name ""
• npm config set init-author-url ""
• npm config set init-author-email ""
• npm config set init-license "ISC"
• npm config set init-version "1.0.0"

custom (example)

• npm config set init-author-name "Tierney Cyren"
• npm config set init-author-url "https://bnb.im"

Need

Convert .mov/.MP4 to .gif

Reason

As a developer, I feel better to upload a short video when I create the pull request to show other viewers what I did in this PR. I tried .mov format directly got after finishing recording screen using Quicktime, however, gif offers preview in most web pages, and has smaller file size.

This is not limited to developer, anyone has this need can use this method to convert the files.

Implicit integers for JavaScript

This proposal is an alternative to “Integer: Arbitrary precision integers in JavaScript” by Daniel Ehrenberg, but it also builds on his work.

Everything mentioned here is work in progress. It is not sure that these ideas will work out:

• They may break the web.
• They may turn out to be too complicated/user-unfriendly.

Array Iteration

https://gist.github.com/ljharb/58faf1cfcb4e6808f74aae4ef7944cff

While attempting to explain JavaScript's reduce method on arrays, conceptually, I came up with the following - hopefully it's helpful; happy to tweak it if anyone has suggestions.

Intro

JavaScript Arrays have lots of built in methods on their prototype. Some of them mutate - ie, they change the underlying array in-place. Luckily, most of them do not - they instead return an entirely distinct array. Since arrays are conceptually a contiguous list of items, it helps code clarity and maintainability a lot to be able to operate on them in a "functional" way. (I'll also insist on referring to an array as a "list" - although in some languages, List is a native data type, in JS and this post, I'm referring to the concept. Everywhere I use the word "list" you can assume I'm talking about a JS Array) This means, to perform a single operation on the list as a whole ("atomically"), and to return a new list - thus making it mu

Module/Script Disambiguation

In the UnambiguousJavaScriptGrammar proposal, Bradley and John-David discussed the challenge of dealing with files that could successfully parse as either scripts or modules but have different execution behavior. This has a couple of issues:

• Code written with the expectation of being executed in one mode could be executed in the wrong mode, without the ability to prevent this kind of erroneous execution.
• Top-level scripts intending to be executed by Node via node myscript.js can't work for files that want to use import syntax, unless Node adds and mandates an un-ergonomic new command-line switch like node -m myscript.js.

Unambiguous Solution

In the UnambiguousJavaScriptGrammar proposal, the language would be changed to require that all module files contain at least one import or export declaration. The easiest way to ensure that a file is a module
