Go is generally better for high-performance, concurrent backend APIs, while TypeScript is superior for full-stack JavaScript ecosystems and rapid frontend-backend integration. Go compiles to a single static binary with built-in concurrency primitives, whereas TypeScript requires a runtime (Node.js) and excels in type safety across the entire JavaScript stack.
// Go: High-performance, compiled, concurrent
package main
import "net/http"
func main() { http.HandleFunc("/", handler); http.ListenAndServe(":8080", nil) }
func handler(w http.ResponseWriter, r *http.Request) { w.Write([]byte("Hello")) }
// TypeScript: Flexible, JS ecosystem, runtime-dependent
import express from 'express';
const app = express();
app.get('/', (req, res) => res.send('Hello'));
app.listen(8080);
