How to call local function outside which declared inside the function?

You cannot, it's declared locally and that's where it's scoped. — connexo

If it's in a TypeScript function, then its TypeScript, not JavaScript (it will work the same way as a JS function since TS is a superset of JS and is usually transpiled to JS) — Quentin

Thanks @connexo. I just declared callUpdate() as local function of create() — Satheesh Srinivasan
