WebAssembly: The Future of High-Performance Web Applications

WebAssembly (abbreviated as Wasm) is one of the most important developments in the world of web development, enabling developers to run code at near-native performance directly in the browser. In this article, we explore how this technology is changing the future of web applications.

What is WebAssembly?

WebAssembly is a binary instruction format for a stack-based virtual machine, designed to be a low-level target for programming languages like C, C++, and Rust, allowing code deployment on the web for execution at near-native speed.

// Example C++ code that gets compiled to WebAssembly
#include

int fibonacci(int n) {
  if (n <= 1) return n;
  return fibonacci(n-1) + fibonacci(n-2);
}
