Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

TrailBase: Fast & Open FireBase alternative
The benchmark sets up a custom HTTP endpoint /fibonacci?n= using the same slow recursive Fibonacci implementation for both, PocketBase and TrailBase. This is meant as a proxy for a computationally heavy workload to primarily benchmark the performance of the underlying JavaScript engines: goja for PocketBase and V8 for TrailBase. In other words, the impact of any overhead within PocketBase or TrailBase is diminished by the time it takes to compute fibonacci(N) for sufficiently large N.

My Contribution to Deno 2.0
Deno (/ˈdiːnoʊ/, pronounced dee-no) is a JavaScript, TypeScript, and WebAssembly runtime with secure defaults and a great developer experience. It's built on V8 Rust, and Tokio.

When to Use Bun Instead of Node.js
In most cases, Bun is faster than Node.js. Zig offers great control over code execution, which allows maintainers to optimize for performance at a low level. Bun is also based on the fast and efficient JavaScriptCore engine. In contrast, Node.js is written in less efficient JavaScript and relies on the slower V8 JavaScript engine.

Show HN: Invertornot.com – API to enhance your images in dark-mode
Semi-related - I saw this trick on https://v8.dev a while back, but `filter: hue-rotate(180deg) invert();` can be a neat CSS trick to 'dark mode' some kinds of graphics. The `hue-rotate` help a bit to keep 'blues blue' etc.
It's far from perfect, but it's a neat trick to be aware of.

Top 8 Recent V8 Updates
V8 is a high-performance JavaScript engine developed by Google. Its purpose is to convert JavaScript code into machine code for execution by the underlying hardware. Primarily developed by the V8 team at Google, the engine focuses on speed and efficiency. In particular, it relies on just-in-time compilation and uses inline caching for high performance.

C++ Specification vs Implementation
Exactly the same as JavaScript engines. Be it Mozilla's SpiderMoneky, Google's V8, Apple's Webkit, or Microsoft's Chakra. No matter how specific we draft a specification there is always room for interpretation. Every team has a different take on what part of a spec is describing. Oftentimes it's just a matter of varying pros and cons of different approaches on the road to matching spec; various teams just kind of have to pick a direction and run with it. Other times a spec is not only too vague, but clearly short-sighted to boot.

Abstract Syntax Trees and Practical Applications in JavaScript
Remember that we earlier established that every source gets parsed into an AST at some point before it gets compiled or interpreted. For example, platforms like Nodejs and chromium-based browsers use Gooogle's V8 engine behind the scenes to run JavaScript and of course, some AST parsing is always involved before the interpreter kicks in. I looked V8's source and I discovered it uses its own internal parser to achieve this.

This year in Servo: over 1000 pull requests and beyond
I thought it would be a fun weird project to make Servo work with MS' abandoned JavaScript engine:
https://github.com/chakra-core/ChakraCore
Of course it is written in C++ and you'd probably want a pure Rust browser. But it is sad seeing that fairly complete open source JIT JavaScript engine sit and rot.

Have you deployed Microsoft Todo to end users? How did you deploy it?
As a Linux user, I very much think Microsoft should have continued Trident and Chakra. Apple also should have continued releasing Safari for Windows. Our web QA setup was entirely built around Macs back then, but it was great to be able to test sites with Safari on Windows, and to have another responsive browser on Win32.

Exploring React Native’s new architecture
Furthermore, the new architecture decouples the JavaScript interface from the engine, enabling the use of other JavaScript engines such as Hermes, V8, or Chakra.

Enumerating and analyzing 40 non-V8 JavaScript implementations
I am astonished at the omission of ChakraCore, open sourced by Microsoft but sadly abandoned by them after they switched Edge to Chromium: https://github.com/chakra-core/ChakraCore. But it looks like it’s still chugging along as a community effort rather than being completely abandoned.
What are some alternatives?
babel-sublime - Syntax definitions for ES6 JavaScript with React JSX extensions.
icr - Interactive console for Crystal programming language
hermes - A JavaScript engine optimized for running React Native.
astexplorer - A web tool to explore the ASTs generated by various parsers.
bun - Incredibly fast JavaScript runtime, bundler, test runner, and package manager – all in one
Jint - Javascript Interpreter for .NET
libuv - Cross-platform asynchronous I/O
V8 - The official mirror of the V8 Git repository
WebKit - Home of the WebKit project, the browser engine used by Safari, Mail, App Store and many other applications on macOS, iOS and Linux.
