Node.js 中使用 async/await 实现 fetchData 后执行 processData

async function fetchData() { return new Promise(function(resolve, reject) { setTimeout(function() { resolve('Data fetched successfully!'); }, 2000); }); }

async function processData() { return new Promise(function(resolve, reject) { setTimeout(function() { resolve('Data processed successfully!'); }, 2000); }); }

async function execute() { await fetchData(); await processData(); }

execute().then(function() { console.log('Both functions executed successfully!'); });
