Then, you can call the readJson function to read a JSON file:

index.ts
async function readMyJsonFile(): Promise<any> {
  try {
    const myObject = await readJson('/path/to/my/json/file.json');
    console.log(myObject);
    return myObject;
  } catch (err) {
    console.error(err);
    return null;
  }
}

Note that we have used the async and await keywords to handle the asynchronous nature of the readJson function.

Also, the readJson function returns a Promise that resolves to the parsed JSON object. Hence, we have used the Promise<any> return type for the readMyJsonFile function.

Finally, we have included error handling using the try and catch blocks to handle any errors that may occur when reading the JSON file.
