v8.dev VS react-native

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.

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.

V8

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.

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.

While Node.js uses Google's V8 engine that power's Chrome browser, Bun uses JavaScriptCore (JSC), which is an open source JavaScript engine developed by Apple for Safari.

While the idea of server-side JavaScript was not novel, what powered Node.js was! The V8 engine, birthed by Google for Chrome, was now driving Node.js, bringing unparalleled speed and performance to JavaScript execution.

V8 JavaScript Engine

Node runs on the V8 JavaScript engine, which handles memory allocation. The entirety of memory used for a running Node application is held in what is known as a Resident Set. This includes:

There was always a tiny sparkle in me telling me that I want to develop mobile apps but I never pursued it. It always felt a bit complicated for me to learn development processes in a completely different industry. I did try developing mobile apps using React Native but it never felt right for me. Also, I already tried to write some Kotlin code and so far I like it, but the whole Android ecosystem is still pretty new to me and I feel there will be a lot to learn. Nevertheless, I will try to learn it in parallel with Elixir but Elixir will be my primary goal, and Kotlin / Android will go along depending on how much time I will have.

Recently, there has been a notable shift in mobile application development practices. Rather than creating separate applications for each native platform, many developers are opting for hybrid mobile frameworks like React Native.

React Native [ https://reactnative.dev/ ]

Versatility: JavaScript is not limited to web browsers. It's used in a variety of environments, including mobile app development (using frameworks like React Native), game development (using libraries like Phaser), and even serverless computing (using platforms like AWS Lambda).

In the competitive landscape of mobile app development, user experience (UX) has emerged as a critical differentiator. React Native, with its robust framework and versatile capabilities, offers developers a powerful toolkit to create seamless and engaging user experiences. This blog post delves into the design principles and best practices in React Native app development, uncovering how developers can elevate user experience to new heights and drive success in the digital realm.

You can find the React Native documentation here and Flutter Documentation here.

Additionally, React Native, an extension of React.js, enables developers to create hybrid mobile applications with ease.

You don’t know what to do with your time while applying the 5th rule? Start small, tiny steps. If you can’t read much, start small, 15 minutes a day reading a technical article or even a book like Effective Java, by Joshua Bloch. You don’t like to read? Create small projects by using a framework you want to learn. Check for example: React framework.
