1Call fs.exists() first, then read the file
2Read process.files
✓Correct answer: Usually you don't: just read it and handle the ENOENT error

Explanation

Checking first creates a race condition: the file can be deleted between the check and the read. Handling the error is simpler and correct. fs.exists is deprecated.
