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: 'no-restricted-syntax' : [ 'error' , { selector : 'ForInStatement' , message...
