TinyGo WASM Multiply Numbers — Tinygo-wasm Code
Multiplies two numbers passed from JavaScript and prints the result.
# tinygo/demo/multiply.go
package main
import (
"syscall/js"
)
func multiply(this js.Value, args []js.Value) interface{} {
a := args[0].Int()
b := args[1].Int()
doc := js.Global().Get("document")
doc.Call("write", a*b)
return nil
}
func main() {
js.Global().Set("multiply", js.FuncOf(multiply))
select{}
}Tinygo-wasm Language Guide
TinyGo WebAssembly (tinygo-wasm) is a lightweight Go compiler designed to build extremely small and fast WebAssembly binaries, enabling Go developers to run applications in browsers, edge devices, IoT systems, and embedded environments with minimal resource usage.
Primary Use Cases
- ▸Running Go code in the browser via WebAssembly
- ▸IoT and microcontroller applications
- ▸Edge computing Wasm modules
- ▸WASI applications in runtimes like wasmtime or wasmer
- ▸Plugins for serverless Wasm platforms (Spin, Fermyon, WasmCloud, etc.)
Notable Features
- ▸Very small Wasm binary sizes (10-20× smaller than standard Go)
- ▸Optimized LLVM-based compiler backend
- ▸Supports Go core features (structs, interfaces, goroutines via async tasks)
- ▸Targets browsers, WASI, and embedded hardware
- ▸Fast compile times and low resource usage
Origin & Creator
TinyGo was created by Ayke van Laethem and the TinyGo community starting in 2018 to make Go viable for microcontrollers, embedded systems, and WebAssembly.
Industrial Note
tinygo-wasm is heavily adopted in constrained environments: IoT, robotics, WebAssembly edge clouds, plugins in serverless Wasm runtimes, and performance-critical Go applications.
