Using async/await with a forEach loop

by

Are there any issues with using async/await in a forEach loop? I’m trying to loop through an array of files and await on the contents of each file.

import fs from 'fs-promise'

async function printFiles () {
  const files = await getFilePaths() // Assume this works fine

  files.forEach(async (file) => {
    const contents = await fs.readFile(file, 'utf8')
    console.log(contents)
  })
}

printFiles()

This code does work, but could something go wrong with this? I had someone tell me that you’re not supposed to use async/await in a higher-order function like this, so I just wanted to ask if there was any issue with this.
