<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>

   }
   .result,.sample {
      font-size: 18px;
      font-weight: 500;
      color: rebeccapurple;
   }
   .result {
      color: red;
   }

<h1>Convert array of comma separated strings to array of object</h1>
<div class="sample"></div>
<br />
<div class="result"></div>
<button class="Btn">CLICK HERE</button>
<h3>Click the above button to convert the above array of strings to objects</h3>
<script>
   let BtnEle = document.querySelector(".Btn");
   let resEle = document.querySelector(".result");
   let sampleEle = document.querySelector(".sample");
   let arr = [
      '{ "name":"Rohan", "age":12}',
      '{ "name":"Mohit", "age":22}',
      '{ "name":"Shawn", "age":18}',
      '{ "name":"Michael", "age":19}',
   ];
   sampleEle.innerHTML = arr;
   BtnEle.addEventListener("click", () => {
      arr.forEach((item, index) => {
         arr[index] = JSON.parse(item);
      });
      arr.forEach((item) => {
         resEle.innerHTML += "Name = " + item.name + " : Age = " + item.age + "<br>";
      });
   });
</script>
