    Usage

    // the second argument (which is context) is optional
    const readFile = promisify(fs.readFile, fs);
     
    readFile(resolve('index.js'), 'utf8')
      .then(console.log)
      .catch(console.error);

    Arguments:

    • fn (function): The original function.
    • ctx (*): Predefines execution context of the original function.
    • ..._ (*): Possibility to provide additional arguments, that will be prepended to the function.
