Scenario : I have a list of Students. I want to filter a student having a specific studentId and update its Marks to say 60 in the list. How can I do that **without using the "update" operator introduced in Mule 4.3**

Student list:

```
[
  {
    "studentId": "781e5dc2-f76b-4e35-ac27-f5835c960083",
    "studentName": "Mr. 1",
    "studentMarks": 1
  },
  {
    "studentId": "cb8a606a-b91c-4697-8d73-84170b156180",
    "studentName": "Mr. 2",
    "studentMarks": 4
  },
  {
    "studentId": "656b247f-a755-476f-a845-b61d28e4be79",
    "studentName": "Mr. 3",
    "studentMarks": 9
  },
  {
    "studentId": "d1cd5ee3-cef6-4d5e-a380-cb5e79495f77",
    "studentName": "Mr. 4",
    "studentMarks": 16
  }
]

```

Student whose marks is to be updated to 60 is with studentId : 656b247f-a755-476f-a845-b61d28e4be79

So After the update the final result should be :

```
[
  {
    "studentId": "781e5dc2-f76b-4e35-ac27-f5835c960083",
    "studentName": "Mr. 1",
    "studentMarks": 1
  },
  {
    "studentId": "cb8a606a-b91c-4697-8d73-84170b156180",
    "studentName": "Mr. 2",
    "studentMarks": 4
  },
  **{
    "studentId": "656b247f-a755-476f-a845-b61d28e4be79",
    "studentName": "Mr. 3",
    "studentMarks": 60
  }**,
  {
    "studentId": "d1cd5ee3-cef6-4d5e-a380-cb5e79495f77",
    "studentName": "Mr. 4",
    "studentMarks": 16
  }
]

```
