React Typewriter with Fetched Text | Dataford Interview Questions

Implement a React component that fetches a JSON payload from a secure HTTP endpoint and renders a text field one character at a time. The component must support configurable typing delay in milliseconds and expose animation controls for start, pause, resume, and reset. Return a component or hook-based implementation that handles loading, fetch failure, timer cleanup, and repeated control actions correctly.

Constraints

0 <= len(text) <= 10^4
1 <= delay <= 10^4
actions contains only "start", "pause", "resume", "reset", or ["tick", n]
0 <= n <= 10^4
The implementation should behave correctly for repeated control actions

Function Signature
