WebAssembly with Go: Powering the Web with Speed and Efficiency
summary
Go compiles to WebAssembly with the concrete command GOOS=js GOARCH=wasm, produces main.wasm, requires the runtime glue file wasm_exec.js, and serves an index.html that fetches and instantiates the module; the demo prints "go web assembly" to the browser console so the pipeline visibly works. Claim: Go+Wasm yields near‑native performance for compute‑heavy front‑end tasks. Tests automate with GOOS=js GOARCH=wasm go test. Real adopters include Figma, Google Earth, Microsoft Blazor, Unity, AutoCAD and Adobe.
