“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.”

These kinds of surveys are usually not very rigorous but I still found the article to be an entertaining read with a few interesting insights.

• “In-place resizable ArrayBuffers”, proposed by Shu-yu Guo
• “ArrayBuffer.prototype.transfer and friends” proposed by Shu-yu Guo, Jordan Harband and Yagiz Nizipli

“[...] 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.”

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.

“regex is a template tag for dynamically creating readable, high performance, native JavaScript regular expressions with advanced features. It’s lightweight (5.5KB), has no dependencies, and supports all ES2024+ regex features.”

“Highlights include using whitespace and comments in regexes, atomic groups via (?>...) which can help you avoid ReDoS, and context-aware interpolation of RegExp instances, escaped strings, and partial patterns.”
