How to check in Node if module exists and if exists to load?

To check in Node if module exists and if exists to load, we can wrap our require call with a try-catch block.

For instance, we write

try {
  const m = require('/foo/bar');
  //  ...
} catch (ex) {
  handleErr(ex);
}

to wrap our require call with a try block.

If the module doesn’t exist, then an error will be thrown, and so we can catch the error with the catch block.
