In the below data array if a user is able to search with Fruits (Category) or Apple (Subcategory).

const data = [
  {
    "category": "Fruits",
    "subCategory": [
      {
        "id": 1,
        "val": "Apple"
      },
      {
        "id": 2,
        "val": "Banana"
      }
    ]
  },
  {
    "category": "Vagitable",
    "subCategory": [
      {
        "id": 1,
        "val": "Tomato"
      },
      {
        "id": 2,
        "val": "Potato"
      }
    ]
  }
]

Output: Search value "Fruits" or "Apple".

const data = [{
"category": "Fruits",
"subCategory": [
{
"id": 1,
"val": "Apple"
}
] }]

You search category and subCategory by find() array manipulation method.

const data = [
  {
    "category": "Fruits",
    "subCategory": [
      {
        "id": 1,
        "val": "Apple"
      },
      {
        "id": 2,
        "val": "Banana"
      }
    ]
  },
  {
    "category": "Vagitable",
    "subCategory": [
      {
        "id": 1,
        "val": "Tomato"
      },
      {
        "id": 2,
        "val": "Potato"
      }
    ]
  }
]

const searchValue = "Tomato";

const output = data.find(items => 
  items.category === searchValue || 
  items.subCategory.some(subItem => subItem.val === searchValue)
);

console.log(output);

you need to use find method to achieve desired solution first we find
in the main array and match with category if not find with category
then check with subcategory

const data = [
  {
    "category": "Fruits",
    "subCategory": [
      {
        "id": 1,
        "val": "Apple"
      },
      {
        "id": 2,
        "val": "Banana"
      }
    ]
  },
  {
    "category": "Vagitable",
    "subCategory": [
      {
        "id": 1,
        "val": "Tomato"
      },
      {
        "id": 2,
        "val": "Potato"
      }
    ]
  }
];
let input="Fruits";
let result = data.find(item => {
    if(item.category == input)
        return item;
    else{
       let ret=[];
       ret.push(item.subCategory.find(item2 => {
           return item2.val == input
        }))
        item.subCategory=ret;
        return item;
    }
});
console.log(result);
