You can use like this. This can be achieved by iterating the object. 

const data = {
              "items":{
                "hotdrinks":[
                  {
                  "id":"9aa113b4-1e4e-4cde-bf9d-8358fc78ea4f",
                  "price":20,
                  "name":"Tea",
                  "img":"../assets/img/HotDrinks/1_udupibhavan.jpg"
                  },
                  {
                  "id":"9aa113b4-1e4e-4cde-bf9d-8358fc78ea4f",
                  "price":25,
                  "name":"Coffee",
                  "img":"../assets/img/Hot Drinks/2_udupibhavan.jpg"
                  },
                  {
                  "id":"9aa113b4-1e4e-4cde-bf9d-8358fc78ea4f",
                  "price":50,
                  "name":"Hot Milk",
                  "img":"../assets/img/Hot Drinks/3_udupibhavan.jpg"
                  },
                  {
                  "id":"9aa113b4-1e4e-4cde-bf9d-8358fc78ea4f",
                  "price":70,
                  "name":"Horlicks",
                  "img":"../assets/img/Hot Drinks/4_udupibhavan.jpg"
                  },
                  {
                  "id":"9aa113b4-1e4e-4cde-bf9d-8358fc78ea4f",
                  "price":80,
                  "name":"Badam Milk",
                  "img":"../assets/img/Hot Drinks/5_udupibhavan.jpg"
                  }
                ]
              }
            }
            

var dataArray = []

for(k in data.items){
  var dataObj = {}
  dataObj.title = k
  dataObj.content = data.items[k]  //You can also access the object values by using bracket ([]) notation
  dataArray.push(dataObj)
  
}

console.log(JSON.stringify(dataArray))

The above expected output json is not valid. We can achieve the following.

[{"title":"Hotdrinks"}, {"content": [  
     {  
        "id":"9aa113b4-1e4e-4cde-bf9d-8358fc78ea4f",
        "price":20,
        "name":"Tea",
        "img":"../assets/img/HotDrinks/1_udupibhavan.jpg"
     },
     {  
        "id":"9aa113b4-1e4e-4cde-bf9d-8358fc78ea4f",
        "price":25,
        "name":"Coffee",
        "img":"../assets/img/Hot Drinks/2_udupibhavan.jpg"
     },
     {  
        "id":"9aa113b4-1e4e-4cde-bf9d-8358fc78ea4f",
        "price":50,
        "name":"Hot Milk",
        "img":"../assets/img/Hot Drinks/3_udupibhavan.jpg"
     },
     {  
        "id":"9aa113b4-1e4e-4cde-bf9d-8358fc78ea4f",
        "price":70,
        "name":"Horlicks",
        "img":"../assets/img/Hot Drinks/4_udupibhavan.jpg"
     },
     {  
        "id":"9aa113b4-1e4e-4cde-bf9d-8358fc78ea4f",
        "price":80,
        "name":"Badam Milk",
        "img":"../assets/img/Hot Drinks/5_udupibhavan.jpg"
     }
  ]}]

If you are okay with this then i'll give you the sample code for the same.
