can we do const filePath = fileOrPath.split(path.posix.sep); here? (or just fileOrPath.split('/'))

Thanks for suggestion. Changed to const filePath = fileOrPath.split('/')

let filePath;

filePath = fileOrPath.replace(/(\/)/g, path.sep).split(path.sep); // ['tmp', 'a.js']

filePath = fileOrPath.split(path.sep); // ['tmp', 'a.js']

const filename = filePath.pop(); // filepath becomes dirPath (no filename)

why not fs.realpathSync()? process.binding seems overkill

fs.realpathSync() does not correct the path.

They differ:

fs.realpathSync(process.cwd()):
C:\Users\pdanis\desktop\projects\my-js-learning\other\temp
(edit: corrected \\projects to \projects)

process.binding('fs').realpath(process.cwd()):
C:\Users\pdanis\Desktop\Projects\my-js-learning\other\temp

If I understand it correctly fs.realpathSync() uses JS fs and process.binding('fs').realpath() is using GetFinalPathNameByHandle() on Windows.

There is a PR, which should expose process.binding('fs').realpath() as fs.realpathSync.native().
nodejs/node#15776

} catch (err) {
// do nothing, just catch error
// process.binding('fs').realpath can throw, e.g. on mapped drives
}
}
