typeover

Learn Go, Zig, and Rust by translating from TypeScript you already understand. Short drills, real syntax, runnable code, and hints only when you ask for them.

Built for developers who don't need another programming intro; they need their TypeScript reflexes reshaped for the next language.

One TypeScript idea, three correct translations

Same TypeScript intent. Different target-language reflexes. Pick any answer; all three are valid in their own language.

count.ts
const count = users.length;
console.log(count);
count := len(users)
fmt.Println(count)

Correct in Go: length is a builtin function, and printing goes through fmt.
