async function printFiles () { const files = await getFilePaths(); await Promise.all(files.map(async (file) => { //耗时操作 const contents = await fs.readFile(file, 'utf8') console.log(contents) })); }
以上是并发操作,如果不想并发,使用for循环做:
async function dbFuc(db) { let docs = [{}, {}, {}]; for (let doc of docs) { await db.post(doc); } }
