Zero-runtime TypeScript. scriptc compiles ordinary TypeScript into small, fast native executables — no Node, no V8, no JavaScript engine in the binary. $ cat fib.ts function fib(n: number): number { return n < 2 ? n : fib(n - 1) + fib(n - 2); } console.log(fib(30)); $ scriptc run fib.ts 832040 $ scriptc build fib.ts && ls -la fib -rwxr-xr-x 178K fib # a self-contained native binary, ~2ms startupNo changes to your code.
