How does fs-promise.access work?

fs-promise.access is a promise-based version of Node.js' fs.access method, used to check if a file or directory exists and can be accessed with the specified permissions. It returns a Promise that resolves if the file or directory exists and the specified permissions are granted, and rejects with an error if the file or directory does not exist or the permissions are not granted.

const fsp = require("fs-promise");

fsp
  .access("/path/to/file")
  .then(() => console.log("File exists"))
  .catch(() => console.error("File does not exist"));

In this example, fs-promise.access is used to check if a file exists at the given path. The method returns a Promise that resolves if the file exists, and rejects if it doesn't.
