• TypeScript 

  • Minimum supported version 4.6 .

  • For even more type-safety and accurate inference, use version 5.4  or later.

  • For improved compilation performance, use version 5.9  or later.

  • You must enable strict mode in your tsconfig.json file’s compilerOptions:

    {
      // ...
      "compilerOptions": {
        // ...
        "strict": true
        // ...
      }
      // ...
    }
