How to rename field inside object-CodePudding

I found some solutions but no exactly what I want. I want to change field name inside object name where condition I will explain by following example for if array=

[{

        "mobile1": [{
            "screensize": "6.5"
        }]
    },
    {

        "mobile2": [{
                "screensize": "6.5"
            },
            {
                "price": "2000"
            }
        ]
    }
]

I want to change mobile1 to newmobile final output will be

[{

        "newmobile": [{
            "screensize": "6.5"
        }]
    },
    {

        "mobile2": [{
                "screensize": "6.5"
            },
            {
                "price": "2000"
            }
        ]
    }
]

With input.map(i => { const {x, ...rest} = i; return x ? {...rest, a: x} : rest}) you should be able to change const input = [{x: 1, y: 2}, {x: 11, y: 22}, {z: 111, y: 222}] into [{y:2,a:1},{y:22,a:11},{z:111,y:222}]. Could this work for you?

Try this:

let c = [{

        "mobile1": [{
            "screensize": "6.5"
        }]
    },
    {

        "mobile2": [{
                "screensize": "6.5"
            },
            {
                "price": "2000"
            }
        ]
    }
]
let final = c.map(i=>{
     let x = Object.getOwnPropertyNames(i)
     if(x=="mobile1"){
     console.log(i.mobile1)
       return {"newmobile":i.mobile1}
     }
     else {
         return i
     }
 })
console.log("final output",final);
