Mengapa Menggunakan WASM? Manfaat Utama

Now the why: WebAssembly is a game-changer for performance. This lesson covers its core advantages and when to actually reach for it.

WASM's biggest draw is near-native speed — almost as fast as code written for your OS. Its binary format runs efficiently, straight on the CPU.

JavaScript is JIT-compiled; WASM is built for ahead-of-time compilation. That means faster startup, predictable performance, and deep static optimization.

WASM is portable: the same module runs in browsers, on servers via Node or standalone engines, even on mobile and embedded devices. Write once, run anywhere.

WASM runs in a strict sandbox, isolated from the host. It can't touch files or network directly — every outside call goes through the host. Safe by design.

WASM is a compilation target, not a language. Write in C, C++, Rust, Go, or C# and compile to WASM — reusing existing code and mature toolchains.

WASM modules are compact — a binary format that compresses tighter than text-based JS. Smaller files mean faster downloads and quicker page loads.

WASM partners with JavaScript: JS owns the DOM and orchestration while WASM handles the performance-critical work. Load and control WASM right from JS.

Reach for WASM for high-performance work: games, video and audio processing, porting C/C++ libraries, cryptography, and cross-platform apps.

Recap of WASM's wins: near-native performance, portability, sandboxed security, multi-language support, and seamless JavaScript integration.
