Is WebAssembly the Future of Web Apps?

The Browser is the new OS

With tools like Figma and Adobe Photoshop Web running in the browser, the demand for high-performance computing on the web is skyrocketing.

Enter WebAssembly

WASM allows us to run code written in languages like C++, Rust, and Go at near-native speed.

// Rust function callable from JS
#[wasm_bindgen]
pub fn fast_calculation(a: i32, b: i32) -> i32 {
    a + b
}

Use Cases

1. Video Editing: Rendering complex timelines.
2. Image Processing: applying filters to 4k images.
3. Gaming: Unreal Engine 5 in the browser.

It's not replacing JavaScript, but it is certainly acting as a superpower sidekick.
