• neha test minimal test framework
• neha init starter template

CLI

• neha init <app-name>
• neha dev
• neha build
• neha check
• neha test

Example (Neha)

le React, { useState } se 'react';

aSync_kaam is not valid; use async_kaam
kaam App(): JSX.Element {
  tay [count, setCount] = useState<number>(0);
  de (
    <button onClick={() => setCount(count + 1)}>
      आपने {count} बार click किया है
    </button>
  );
}
