Which of these correctly reads a file asynchronously using promises?

A fs.readFileSync(path)
B await fs.promises.readFile(path)
C fs.read(path)
D require('fs').get(path)

Answer

await fs.promises.readFile(path)

fs.promises provides the promise-based API. It should be used for anything on a request path so the event loop stays free.
