One of WebAssembly's long-awaited promises is to allow languages other than j**ascript in web browsers. Pyscript provides a full Python runtime in the browser, allowing you to use Python as a full-fledged scripting language in your web pages. There is even support for some advanced libraries, such as numpy, which allows you to build powerful and complex applications using a native HTML frontend without the need for a Python server on the backend. Note that pyscript is currently experimental and fragile, often taking a long time to start. But as a peek into the future, pyscript is tempting, and it opens the door to many possibilities. However, WebAssembly's promise is not limited to Python. Its goal is to compile any language into a binary format to run efficiently in the browser. This means that we can see a greater variety of languages being used in the browser, not just j**ascript. For example, WebAssembly already supports statically typed languages such as C++ and Rust, and is constantly expanding support for other languages.
This will open up unprecedented possibilities for web development. We can imagine a world where web pages are no longer just the domain of j**ascript, but can be built and run in a variety of languages. Not only does this mean more options, but it can also lead to more efficient execution and fewer bugs.
But at the same time, it can also present some challenges. Different languages may have different runtime requirements and performance characteristics, which can affect the performance and load time of web pages. In addition, browsers need to support binary formats in various languages, which can add complexity to the browser.
Still, the potential of WebAssembly is enormous. It could change the way we build and run web applications, allowing us to leverage more programming languages and tools to build web pages. It's an exciting future and we look forward to WebAssembly's growth and maturity.
