Question - What is the difference between readFile and createReadStream in Node.js?
Answer -
• readFile: This is used to read all of the contents of a given file in an asynchronous manner. All of the content will be read into the memory before users can access it.
• create ReadStream: This is used to break up the field into smaller chunks and then read it. The default chunk size is 64 KB, and this can be changed as per requirement
