What is Web Assembly and How it fits into Web Development?

Web assembly is a new concept compatible in running different modern web browsers. The major benefit of WebAssembly is the rapid gain in performance and application of the code. It has been designed to be an effective compilation target for source languages like C, C++, Rust, etc.

Web Assembly provides a way to run code written in multiple languages on the web at native fast speed, with client apps running on the web applications.

WebAssembly is designed to run alongside JavaScript — using the WebAssembly JavaScript APIs. With WebAssembly you can load WebAssembly modules into a JavaScript app and share both functionalities This allows you to take advantage of WebAssembly’s performance and power, alongside not losing JavaScript’s expressiveness and flexibility. The best thing about web assembly is that you don’t need to write code to use it. All you need to import it into a web (or Node.js) app, exposing WebAssembly functions for use via JavaScript.

Being a different language than JavaScript, but it’s not intended to replace JavaScript. The use of web Assembly makes it easier for the code to run onto different browsers. It is designed to complement and work alongside JavaScript, allowing web developers to take advantage of both languages’ strong points.

• JavaScript is a high-level language used for coding for decades. It is flexible and expressive enough to write web applications. Among all, its advantages the dynamically typed, no compile setup, and has a huge ecosystem of powerful frameworks, libraries, and other tools.
• WebAssembly resembles with assembly-like language with a compact binary format. It provides near-native performance and functionality with low-level memory models such as C++ and Rust with a compilation target so that they can run on the web.

WebAssembly tends to be more than a web-based solution. In time, as the specification of WebAssembly spec shapes up and more features come into the light, it will be surely become useful in desktop apps, servers, mobile apps, and other execution environments. Enabled by WebAssembly, the future of web development is:

1. Linguistically Diverse
2. Extremely Fast
3. Parallel

This is a common question of whether web assembly is going to kill JavaScript or not. The simple answer to this question is No. At least, in the next 5-10 years, it’s not possible. WebAssembly is not intended to take over JavaScript completely. JavaScript has unique significance like WebAssembly has. Both are not intended to replace each other, instead, WebAssembly fills the gap that JavaScript has left.

WebAssembly is being used by some of the most prominent names such as TensorFlow, unity, AutoCAD, Google Earth, blazer, and Yew, etc.

The Features of Web Assembly have the unlimited capability to turn the tables of development.

In a nutshell, we can say that:

WebAssembly and JavaScript are not friends nor foes, they’re allies in making web development better.

WASM or web Assembly wasn’t meant to optimize your website in any way. It is built with and idea of to take browsers to the next level of customizations and functionalities when performing tasks such as:

• Game development
• AR / VR live applications
• Music editing and streaming
• Platform emulation
• Video editing
• Image recognition
• Encryption
• Virtual private network

And a lot more heavy-duty tasks.

In the recent years, there’s huge exploration of frameworks, compilers and other types of solutions are promises to make the codes web compatible. But all have some or many complications while working with JavaScript. Most of them needs serious debugging to keep codes alive, except Web Assembly.

Web Assembly has put serious impacts on JavaScript to make it more reliable and compatible and feature filled. Hence, web development with assembly is extreme rich solutions and Hence, it can be called that web Assembly is the future of web development.
