WebAssembly (Wasm) is a new type of code that is designed to run on modern web browsers. It is a low-level binary format that is designed to be executed efficiently by web browsers. Wasm is a game-changer for web development because it allows developers to write code in languages other than JavaScript, such as C++ and Rust, and run that code on the web.

Why WebAssembly Instead of JavaScript?

WebAssembly was designed to be faster and more efficient than JavaScript. It can be compiled ahead-of-time, which means that it can be loaded more quickly and executed more efficiently than JavaScript. It is also designed to be more secure than JavaScript because it runs in a sandboxed environment, which means that it cannot access the user's file system or other sensitive data.

WebAssembly is not intended to replace JavaScript, but rather to complement it. JavaScript is still the primary language used for web development, and it will likely remain so for the foreseeable future. However, WebAssembly can be used in conjunction with JavaScript to create more powerful and efficient web applications.

Why can't we use it to build a small application?

While WebAssembly can be used to build small applications, it is not always the best choice. For small applications, JavaScript is often faster and easier to use. However, for large applications that require high-performance and low-level access to system resources, WebAssembly is a better choice.

Why is it hard to convince web developers to learn C++ or Rust?

Many web developers are not familiar with C++ or Rust, and it can be challenging to convince them to learn these languages. However, the benefits of using WebAssembly are significant, and many developers are starting to see the advantages of using it.

One of the main advantages of using WebAssembly is that it allows developers to write high-performance code that can be executed quickly and efficiently. This is essential for large applications that require complex calculations and data processing. Another advantage is that WebAssembly allows developers to reuse code that has already been written in C++ or Rust, which can save time and reduce development costs.

Conclusion

WebAssembly is a new technology that is changing the way we think about web development. It offers developers the ability to write high-performance code in languages other than JavaScript, which can be executed quickly and efficiently on the web. While there is still much to learn about WebAssembly, it is clear that it has the potential to revolutionize web development and open up new possibilities for creating powerful and efficient web applications.
