Rust growing fastest, but JavaScript reigns supreme

thenewstack.io

“Rust is the fastest-growing programming language, with its developer community doubling in size over the past two years, yet JavaScript remains the most popular language with 25.2 million active developers, according to the results of a recent survey.”

JavaScript Promises from the ground up

www.joshwcomeau.com @joshwcomeau@front-end.social

“[...] in this tutorial, we’re going to learn about Promises, but we’ll start at the beginning. I’ll share all of the critical bits of context that took me years to understand. And by the end, hopefully, you’ll have a much deeper understanding of what Promises are and how to use them effectively.”

How to use Corepack

www.totaltypescript.com github.com/mattpocock

According to Corepack’s documentation, it is “an experimental tool to help with managing versions of your package managers. It exposes binary proxies for each supported package manager that, when called, will identify whatever package manager is configured for the current project, download it if needed, and finally run it.”.

This blog post gives a quick introduction to this tool.

Interesting npm packages
