javascript i want to do the opposite of settimeout code example

Example 1: javascript set timeout

var timeToWait = 3000; // 1000 = 1 second
setTimeout(() => {
	console.log("Text printed after 3 seconds");
}, timeToWait);

Example 2: javascipt delay

async function delay(delayInms) {
      return new Promise(resolve  => {
        setTimeout(() => {
          resolve(2);
        }, delayInms);
      });
    }
    async function sample() {
      console.log('a');
      console.log('waiting...')
      let delayres = await delay(3000);
      console.log('b');
    }
    sample();
