JavaScriptでオブジェクトを含む配列の配列をループするにはどうすればよいですか？

以下は、JavaScriptのオブジェクトを含む配列の配列をループするコードです-

例

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
<style>
   body {
      font-family: "Segoe UI", Tahoma, Geneva, Verdana, sans-serif;
   }
   .result {
      font-size: 18px;
      font-weight: 500;
      color: rebeccapurple;
   }
</style>
</head>
<body>
<h1>Loop through array of arrays containing objects in JavaScript</h1>
<div class="result"></div>
<button class="Btn">CLICK HERE</button>
<h3>
Click the above button to loop throught the arrObj
</h3>
<script>
   let BtnEle = document.querySelector(".Btn");
   let resEle = document.querySelector(".result");
   let arrObj = [
      [
         { name: "Rohan", age: 22 },
         { name: "Mohan", age: 12 },
         { name: "Shawn", age: 14 },
      ],
      [
         { id: 12, price: 44 },
         { id: 23, price: 45 },
         { id: 91, price: 14 },
      ],
   ];
   BtnEle.addEventListener("click", () => {
      arrObj.forEach((item) => {
         item.forEach((object) => {
            for (let i in object) {
               resEle.innerHTML += i + " : " + object[i] + " ";
            }
            resEle.innerHTML += "";
         });
      });
   });
</script>
</body>
</html>
