Emscripten vs Rust: What are the differences?
Introduction:
Emscripten and Rust are both popular tools for web development, each with its own unique features and advantages. Understanding the key differences between Emscripten and Rust can help developers choose the right tool for their specific project needs.
Language Compatibility: Emscripten allows developers to compile C and C++ code into JavaScript, making it easier to convert existing codebases for use on the web. On the other hand, Rust is a standalone programming language that provides low-level control similar to C and C++, with a focus on safety and performance.
Performance and Efficiency: Emscripten relies on a complex compilation process to translate C/C++ code to JavaScript, which can impact performance. Rust, on the other hand, boasts better performance and efficiency due to its modern language design and memory management system.
Memory Management: Emscripten requires developers to manage memory manually, which can lead to potential memory leaks and bugs. Rust, on the other hand, uses a sophisticated ownership system to track and manage memory, ensuring safety and preventing common memory-related errors.
Community and Ecosystem: Rust has a vibrant and growing community of developers, with strong support for libraries and tools. Emscripten, on the other hand, has a smaller community focused specifically on compiling C/C++ code to JavaScript for web development.
Learning Curve: Emscripten may be easier for developers familiar with C/C++ to use, as it allows for the direct translation of existing code. Rust, however, has a steeper learning curve due to its unique ownership system and borrow checker, which can be challenging for beginners.
Toolchain Integration: Emscripten integrates seamlessly with traditional C/C++ development tools and workflows, making it a convenient choice for developers already experienced in those languages. Rust, on the other hand, requires a separate toolchain and build process, which may require additional setup and configuration.
In Summary, Understanding the differences between Emscripten and Rust is crucial for developers looking to choose the right tool for their web development projects.
So, I've been working with all 3 languages JavaScript, Python and Rust, I know that all of these languages are important in their own domain but, I haven't took any of it to the point where i could say I'm a pro at any of these languages. I learned JS and Python out of my own excitement, I learned rust for some IoT based projects. just confused which one i should invest my time in first... that does have Job and freelance potential in market as well...
I am an undergraduate in computer science. (3rd Year)
I would start focusing on Javascript because even working with Rust and Python, you're always going to encounter some Javascript for front-ends at least. It has: - more freelancing opportunities (starting to work short after a virus/crisis, that's gonna help) - can also do back-end if needed (I would personally avoid specializing in this since there's better languages for the back-end part) - hard to avoid. it's everywhere and not going away (well not yet)
Then, later, for back-end programming languages, Rust seems like your best bet. Its pros: - it's satisfying to work with (after the learning curve) - it's got potential to grow big in the next year (also with better paying jobs) - it's super versatile (you can do high-perf system stuff, graphics, ffi, as well as your classic api server) It comes with a few cons though: - it's harder to learn (expect to put in years) - the freelancing options are virtually non-existent (and I would expect them to stay limited, as rust is better for long-term software than prototypes)
I suggest you to go with JavaScript. From my perspective JavaScript is the language you should invest your time in. The community of javascript and lots of framework helps developer to build what they want to build in no time whether it a desktop, web, mobile based application or even you can use javascript as a backend as well. There are lot of frameworks you can start learning i suggest you to go with (react,vue) library both are easy to learn than angular which is a complete framework.
And if you want to go with python as a secondary tool then i suggest you to learn a python framework (Flask,Django).
I chose Golang as a language to write Tango because it's super easy to get started with. I also considered Rust, but learning curve of it is much higher than in Golang. I felt like I would need to spend an endless amount of time to even get the hello world app working in Rust. While easy to learn, Golang still shows good performance, multithreading out of the box and fun to implement.
I also could choose PHP and create a phar-based tool, but I was not sure that it would be a good choice as I want to scale to be able to process Gbs of access log data
