How to read file with async/await properly?

Question

I cannot figure out how async/await works. I slightly understands it but I can\'t make it work.

Answer 1

You can easily wrap the readFile command with a promise like so:

async function readFile(path) {
    return new Promise((resolve, reject) => {
      fs.readFile(path, 'utf8', function (err, data) {
        if (err) {
          reject(err);
        }
        resolve(data);
      });
    });
  }

then use:

await readFile("path/to/file");
