Function readJson

Asynchronous function that reads a JSON file from the specified file path.

Throws

If the file does not exist or if there is an error reading the file.

• This code defines an asynchronous function called readJson that reads the content of a JSON file from the specified file path.
• It uses the open function from the fs/promises module to open the file, creates a read stream from the file handler, and reads the file in chunks.
• The chunks are concatenated into a buffer, which is then converted to a string using the UTF-8 encoding.
• Finally, the string is parsed as JSON and returned.

   .then((jsonContent) => {
     console.log(jsonContent);
   })
   .catch((error) => {
     console.error(error);
   });
