Is Rust The Future of JavaScript?

Rust is one of the most hyped-up languages right now.

What exactly is RUST?

Rust is a backend development language that performs very close to C/C++ and solves another headache of C/C++ developers that is Memory Management. Rust is being used by many big companies like AWS, Cloudflare, Next.js, etc.

So why is Rust being called the future of Javascript? 

Javascript has many libraries and transpilers but the main problem with them is that they are also written in Javascript, Javascript itself is not slow but in CPU intensive tasks it slows down a lot. This is where technologies like Rust come in, Rust is way faster maybe 10-100x faster! Rust compiles the code into WASM and executes it in the browser at near-native speeds.

You as a Web Developer won’t need to start learning Rust. However, if you are working on improving the developer experience for example by working on WebPack, SWC, etc. If you know Rust it will be a game-changer for you, you can directly jump into these big companies and projects and help ship these tools to millions of people who use them on a daily basis. Rust is an important language because it helps Javascript indirectly.
