如何在Node.js中使用time.sleep？

Question

我正在尝试在nodejs中使用time.sleep(1)之类的东西，

这是我的代码

const Web3 = require('web3')
const web3 = new Web3('ws://127.0.0.1:8546')

async function main() {
  const batch = new web3.BatchRequest();
  for (let i = 0; i < 1; i++) {
    for (let i = 0; i < 1000; i++) {
      const tx = web3.eth.sendTransaction.request(
        {
          from: web3.utils.toChecksumAddress("0xa00ce1f7fbf8298f4163ab23de8752942bdff98e"),
          to: web3.utils.toChecksumAddress("0xa00ce1f7fbf8298f4163ab23de8752942bdff98e"),
          gas: 21000,
          gasPrice: 1000000000,
          value: 1
        }
      )
      batch.add(tx)
    }
    batch.execute();
    // time.sleep(1) should go here
  }
}
main()

谢谢！
