for loop in javascript - promise - .eslintrc for "for of"

the vast majority of cases map, forEach, find etc. can be used. 

async function printFiles () {
  const files = await getFilePaths();

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

const inventory = [
  {name: 'apples', quantity: 2},
  {name: 'bananas', quantity: 0},
  {name: 'cherries', quantity: 5}
];

const result = inventory.find( ({ name }) => name === 'cherries' );

 function getFirstMatching(array) {

    for (let item of array) {
        const result = heavyTransform(item);
        if (result) {
            return result;
        }
    }
}

Specifically this shuts down the whole no-restricted-syntax. If you want to cherry-pick, here is the current definition:
