How to use built in priority queue in javascript?

const taskQueue = [];

function enqueueTask(task, priority = 0) {
  taskQueue.push({ task, priority });
  taskQueue.sort((a, b) => a.priority - b.priority);
}

async function processQueue() {
  while (taskQueue.length > 0) {
    const { task, priority } = taskQueue.shift();
    const startTime = performance.now();
    await task();
    const endTime = performance.now();
    const executionTime = endTime - startTime;
    console.log(`Task with priority ${priority} executed in ${executionTime.toFixed(2)} ms`);
  }
}

function task1() {
  return new Promise(resolve => {
    setTimeout(() => {
      console.log("Executing Task 1");
      resolve();
    }, 2000);
  });
}

function task2() {
  console.log("Executing Task 2");
}

function task3() {
  return new Promise(resolve => {
    setTimeout(() => {
      console.log("Executing Task 3");
      resolve();
    }, 1500);
  });
}

function task4() {
  console.log("Executing Task 4");
}

enqueueTask(() => task1(), 2);
enqueueTask(() => task2(), 1);
enqueueTask(() => task3(), 3);
enqueueTask(() => task4(), 0);

processQueue();
