how to get the value in any way if key does match with "Item"

   const data = [{
            "Item-55566": "phone",        
        },
        {
            "Items-44555": "Case",       
        }
    ];
    
    /* How to get value if index found by Item */
    
    for(let i = 0; i<data.length; i  ) {
        console.log(data[i].includes("Item"));
        //Expecting phone and case
    }

for-in allows you to loop through the keys in an object. Not to be confused with for-of, which loop through elements in an array.

const data = [{
          "Item-55566": "phone",        
      },
      {
          "Items-44555": "Case",       
      }
 ];
 
for(let datum of data)
{
  for(let key in datum)
  {
    if(key.includes("Item"))
    {
      console.log(datum[key]);
    }
  }
}

If you want to keep your loop you do it with Object.keys and values:

   const data = [{
            "Item-55566": "phone",        
        },
        {
            "Items-44555": "Case",       
        }
    ];
    
    /* How to get value if index found by Item */
    
    for(let i = 0; i<data.length; i  ) {
        if(Object.keys(data[i])[0].includes('Item')){
            console.log(Object.values(data[i])[0]);
        }
    }

In the simple way just change data[i].includes("Item") to data[i].keys().includes("Item").

BUT! Could we have some alternative data set here? For example:

const data = [{
        "Item-55566": "phone",
        "SomeKey: "Some Value",
        123123: "Numeric key with value"
    },
    {
        "Items-44555": "Case",
        "Another-key": "Another value"
    }
];

In this case you need to put some changes in your code to find correct keys & values:

for(let i = 0; i<data.length; i  ) {
    data[i].keys().forEach(v=>{ 
      String(v).includes("Item") && console.log("Got index: ${i}, key: ${v}, value: ${data[i][v]}") 
    })

}

You can use .filter to filter all items of the data array which includes Item text.

Then you can use .map to render new value from each object comes from data array.

const data = [
{"Item-55566": "phone", }, 
{ "Items-44555": "Case",},
{ "Other-44555": "Nope",}];
var filteredItems = data.filter(item => Object.keys(item)[0].includes("Item"));  

console.log(filteredItems.map(item => Object.values(item)[0]));

The for loop iterates through the two objects, so you can check to see whether the object has that particular property using hasOwnProperty()

const data = [

{ "Item-55566": "phone", }, { "Items-44555": "Case", }, ];

/* How to get value if index found by Item */

for (let i = 0; i < data.length; i ) {

if (data[i].hasOwnProperty("Item-55566")) {
console.log(data[i]);

} }
