getSystemErrorMap
Returns a Map of all system error codes available from the Node.js API. The mapping between error codes and error names is platform-dependent. See Common System Errors
for the names of common errors.
fs.access('file/that/does/not/exist', (err) => {
const errorMap = util.getSystemErrorMap();
const name = errorMap.get(err.errno);
console.error(name); // ENOENT
});
