2. Crie o tsconfig.json ficheiro para transpilar o código TypeScript e copie o seguinte código para ECMAScript.

   {
       "compilerOptions": {
         "module": "NodeNext",
         "target": "ES2022", // Supports top-level await
         "moduleResolution": "NodeNext",
         "skipLibCheck": true, // Avoid type errors from node_modules
         "strict": true // Enable strict type-checking options
       },
       "include": ["*.ts"]
   }
   

3. Definições de tipos de instalação para Node

   npm i --save-dev @types/node
   

4. Transpile de TypeScript para JavaScript.

   tsc
   

5. Execute o código com o seguinte comando:

   node index.js
